Here is the application Pleione 3.0 !

 

Installing Pleione 3.0

 

The Pleione 3.0 does not take over the existing data during installation. So if youve used the other version of Pleione, you have to save (copy to another folder) your own personalized data (observer.dat, instruments.dat, observations.dat, list.dat), before installing the newer version. Eventualy you can save also the reports, although they can prepare it at any time.The config.ini contains other data, so the configuration file of previous versions can not be used.

Of course before installing the newer version the older one has to be uninstalled, using the Control Panel. During uninstallation will be deleted the files, which are installed by setup.exe, and will remain those files which were not installed during the installation (eg. Tycho catalogue, charts, reports). After installing the newer version you have to copy the previuosly saved files into the appropriate folder overwriting the installed data files. You have to change the version number in the observer.dat file, in row # = SOFTWARE Pleione version 3.0 by Matyas Csukas.

 

Eliminated the first message box

 

The first message box was removed - with the number of variable stars in the list. This data appear in the greeting window of Pleione.

 

Using AAVSO Bulletin

 

One of the important updates is: they will appear predictions in first column for long- period variables, if they are in your list, based on AAVSO Bulletin.

There are three conditions: 1. You have to download the AAVSO Bulletin and save it in *.HTML format; 2. You have to set the path for saved AAVSO Bulletin in File menu; 3. The star has to be included in the AAVSO Bulletin. There is such a file  in C:\Program Files\PikeSoft\Pleione 3.0\Observer\ directory after installation for example.

If all the above conditions are met, the first column (before the stars name) shows the variable’s three-month prediction (for previous, current and next month), after restarting the program. The + means the star is brighter than visual magnitude 11.0, the (space) means the variable is between 11.0 mg and 13.5 mg, while - means the star is fainter than magnitude 13.5. The ↑ and ↓ arrows indicate if the variable is rising or fading. If you see the MAX or min abbreviation, accompanied by a number, you understand the star is in maximum or in minimum at the given date.

If the variable stars is not found in the AAVSO Bulletin the prediction will include only question marks. For binocular variables before the question mark the + sign will be used, because these stars are always  brighter than magnitude 11.0.

The variables can be filtered by predicted brightness. The user can combine the different brightness ranges. This filter can be used together with other filters (for constellations and observed variables).

If you want only the bright variable stars will be appear in the list.

Shortcut Keys

 

We could use only the mouse in previous versions. In the latest version you can use  keys as well. Heres a list of the main window shortcut keys:

-       A or a – change to AAVSO chart

-       B or b – toggle on/off the Bayer & Flamsteed designations on the finder chart

-       C or c – toggle on/off  the clock

-       D or d – toggle on/off the deep sky objects on the finder chart

-       F or f – change to finder chart

-       N or n – set the orientation of finder chart, north is up

-       O or o – open the Observation Recorder window

-       R or r – refresh the list

-       V or v – toggle on/off the night view mode

-       Z or z - set the orientation of finder chart, zenith is up

-       + – increase the limit magnitude on finder chart

-       - – decrease  the limit magnitude on finder chart

-       * – zoom in the finder chart and the AAVSO chart

-       / - zoom out the finder chart and the AAVSO chart

 

The list of the Observation Recorder window shortcut keys:

-       [Enter] – entering observation (same with clicking on the Add button), after you have typed the magnitude value, so the”focus” is on the ’Mag.’ text box.

If the ”focus” is on one of the Add, Modify or Delete buttons:

-       [Enter] – closes the window (same with clicking on the Close button)

-       [Ctrl] + [Enter] – change the last observation (same with clicking on the Modify button)

-       [Backspace] or [Delete] – delete the last observation (same with clicking on the Delete button)

-       C or c – check/uncheck the Clear variable star name from textbox checkbox

-       L or l – check/uncheck the Clear variable star from list checkbox

-       U or u – check/uncheck the Make variable star name UPPERCASE’ checkbox

 

New Features on Finder Chart

 

One of the most eye-catcher feature is the drawing of two lines on the finder chart, which represents the horizon and the so-called "Invisible horizon", if the variable star is near the horizon.

Another important new feature is the posibility of setting the field of view size and the limit magnitude for different levels of finder chart. To do this, you must click on ’Level Settings’ submenu from the Display menu. These values are saved when the software is closing, if you want. The actual sizes of the field of view are visible on Field of View buttons, while the limit magnitude are displayed as infotip when you hover the mouse pointer over the button.

You can set the maximum number of field stars on finder chart in Pleione 3.0. This value is also saved when the program is closing, if you want. When a finder chart is generating, the software load the data of stars which are in the selected variable star neighborhood. It depends from size of filed of view if a star is or not in the variable neighborhood. The larger the field of view, the more stars will belong to neighborhood of the variable star. The number of field stars depends also on the environment of variable: near the Milky Way will be more filed stars than away from galactic equator. If the number of field stars are greater than the maximum of field stars, the application will use the next level of finder chart (as in previous versions). From this point of view is better if the maximum number of filed stars is higher. But this can slow the running of software on computers with lower performance. Therefore, from this point of view this number should be the smallest as possible. In previous versions this number was constat with the value of 50000. In the current version, this value is the default setting, but the user has the opportunity to change it in the ’Number of Stars on Chart Finder submenu of Display menu.

You can select another variable star also on finder chart, if you click on it. The finder chart will be generated after clicking. If you kepp pressed the [Shift] key while you click, the AAVSO chart will appear instead of finder chart.

If the text box is used to select variable this works inversely: the AAVSO chart will appear after you press the [Enter] key, and the finder chart will be generated when you press the [Shift] + [Enter] keys.

Another small detail: the mouse pointer changes to waiting mode when the finder chart is generating, as well as a night view chart is preparing for an AAVSO chart.

 

Indexing the list

 

The list will „jump” to the variable star after its selection using the text box or the finder chart, not as the previous versions.

 

Use the mouse on  the AAVSO chart

 

If the AAVSO chart is so large that the scrollbars appear, and you click on the chart, the given point will be moved to the center of the chart area – if this is possible.

 

Limit magnitude for observations

 

To reduce the chance for recording an erroneous observation, we have to set a limit magnitude, which serves to prevent the recording of observations which is fainter than this limit. We need to select the Limit magnitude submenu of Observations menu. This value is displayed in the Observation Recorder’ window.

 

The Moon

 

The lunar phase is now graphically displayed too, beside other details of the moon.

The older versions used the geocentric coordinates of the Moon for calculation of its rising, transiting and setting time, and for drawing the Moon on finder chart. The Pleione 3.0 already uses the Moon’s topocentric coordinates. This needs the elevation of observer’s location in addition to geographic coordinates. This data can be given in the observer window (Observer menu > Settings ... submenu > Location tab). Of course, this information is also displayed between the information below the list.

 

The new version of Pleione can be downloaded from here.

I am still waiting for comments and bug reports. Please send it to the csukas.matyas@gmail.com e-mail address.

Clear skies!

Whats New In The Application Pleione 2.0

 
 
The Installation Of Pleione

The Pleione 2.0 does not take over the existing data during installation. So if youve used the other version of Pleione, you have to save (copy to another folder) your own personalized data (config.ini, observer.dat, instruments.dat, observations.dat, list.dat), before installing the newer version. Eventualy you can save also the reports, although they can prepare it at any time.
Of course before installing the newer version the older one has to be uninstalled, using the Control Panel. During uninstallation will be deleted the files, which are installed by setup.exe, and will remain those files which were not installed during the installation (eg. Tycho catalogue, charts, reports). After installing the newer version you have to copy the previuosly saved files into the appropriate folder overwriting the installed data files.

 
Deep-Sky Objects On The Finder Chart

Pleione 2.0 already use NGC catalog, so the software shows the existing deep sky objets in the filed of finder chart. This feature can be switch on / off using the Deep Sky ON / OFF button or clicking on the same named submenu of Display menu. You can set the color of the deep-sky objects and their names only if the night view mod is switched off.

Pleione 2.0

The NGC catalog (ngc2000.dat) can be downloaded from the ftp://cdsarc.u-strasbg.fr/pub/cats/VII/118/ site and it is saved in the Catalogues folder, together with the other catalogues. Another file is also included here, it contains the Messier catalogues number corresponding of NGC objects (ngcm.dat). This file is a modified version of names.dat file, which is available on the site mentioned before.

 
Verifying The Daylight Saving Time

The observer’s settings contains the usage of daylight saving as well. If this is not identical with the daylight saving setting of computers operating system, it will appear a message about the difference and offer the opportunity to adjust it when the program starts.

 
Filtering the list of variable stars

The Pleione 2.0 gives the possibility to filter the list of visible variable stars.
One option is to filter the list by constellation. The user selects the desired constellation in the Constellation drop-down list (combobox), which makes to appear only the stars belonging to selected constellation in the list of visible variables. We have to use the (all) value to unfilter the list.
Another option is to filter out the observed variables. If there are several long period variable stars in the observer’s list, and some of them have been observed in the previous days, these variables must not to observe again. But if they are not deleted from the observer’s list they will be appear on the display. So using this filter, those variable which were observed in the last ’n’ days will not appear in the list of visible variable stars. You can set the number of days (’n’) in the textbox above the list. Of course, the two filters can be used simultaneously.

 
Let’s talk about the AAVSO charts

If you select a variable, a list of available AAVSO charts will appear – which are located in the AAVSO_Charts folder. In earlier versions of Pleione, this list contains only one element, if there exists a chart with parameters you set with AAVSO chart radio buttons. The Pleione 2.0 add all charts of the star to the list, and if there is one with parameters aforementioned between them, it is displayed.
At the first usage of a chart before appearing the night view of the chart is created. It takes a few seconds. This can be uncomfortable in day view mode. Therefore, this function can be turned off. You can do this (or the opposite) by clicking on Generate night view chart submenu in the Display menu.

 
The status of deleting message

When a variable is deleted from the list (either because you do not want to observe it, or because you already have observed it) you receive a message about it. This feature can be turned off if you click on Deleting message submenu in the the Display menu. This is nothing new. The new is that this setting is saved and the next time you run Pleione it will be applied.

 
Number of observations and a new statistical data

The version 2.0 of Pleione displayis the number of observations recorded in current session under the map area in the lower right corner, which data was available only with Observations → Statistics → Current Session module so far.
When the software is closing, can be read at the number of recorded observations and how much time they were made. As new data is included the average time spent on the observation of a star in minutes.

The new version of Pleione can be downloaded from here.

Whats New In The Application Pleione 1.1

 
The installation Of Pleione

The Pleione 1.1 does not take over the existing data during installation. So if youve used the Pleione 1.0, you have to save (copy to another folder) your own personalized data (config.ini, observer.dat, instruments.dat, observations.dat, list.dat), before installing the newer version. Eventualy you can save also the reports, although they can prepare it at any time.
Of course before installing the newer version the older one has to be uninstalled, using the Control Panel. During uninstallation will be deleted the files, which are installed by setup.exe, and will remain those files which were not installed during the installation (eg. Tycho catalogue, charts, reports). After installing the newer version you have to copy the previuosly saved files into the appropriate folder overwriting the installed data files.

 
Variable Stars Which Are Not In The GCVS Catalogue

The Pleione 1.0 version recognizes only those variable stars which are included in the GCVS catalogue. But what should you do if you want to observe a nova or supernova, which will be added to the catalog later? Or, if you want to observe a suspected variable (NSV)?
The most important development in the Pleione 1.1 version is that you can add to the list (the list.dat data files) any variable, regardless if it is or it is not included in the GCVS catalogue. In this case you have to insert a * before the variable star’s name, and you have to give the star’s data like coordinates of stars and other information. The data must be separated from each other with | symbol and this symbol has to be at the end of the line. For example:
*N SGR 2012 NO. 4|18|20|27.26|-27|44|3.26|M|7.77|<17.0|peri|
*NSV 650|01|54|34.24|+68|09|04.4|IA:|6.9|7.7|peri|

The coordinates have read splited in hours, minutes and seconds (in the case of RA) or in degrees, minutes of arc, arc-seconds (for the declination). All values are among the | character is, without any spaces. You must to write the sign + or - for the degrees value of declination. These data have to be given properly, else the software stops with an error message. The other dta are informative, they will not be processed, just will be written on the screen. If you do not know the data, you can leave blank or you can write something there. In the following example the minimum value is not given, and for the period is written the - sign (in the previous examples, for period was given the word peri):
*N SGR 2012 NO. 4|18|20|27.26|-27|44|3.26|M|7.77|-||

 
Approval Of The Refreshing

The refreshing of the list is done automatically in the Pleione 1.0 (if the clock is activated). The user receives a message before each refreshing, which can only take note – pressing the OK button.
In the Pleione 1.1 a Cancel button is also displayed beside the OK button. So the user has the opportunity to refuse the list’s refreshing with this button. In this case the list of observable variables remains the same with unchanged data, but the countdown of refreshing is restarted. This is useful when youre recording observations, and you do not want to interrupt this process.

 
Correcting Errors

Those problems which have detected so far, have been corrected. They are as follows:
The behavior of the table: in the Pleione 1.0 the table behaves incorrectly (not that variable is selected, on which the user was clicked), after it is rearranged by clicking on one field of header, and the list was sorted by respective column.
The Observations Viewer worked incorrectly (it did not show any data) if we wanted to see the current recorded observations (Observations → Viewing → Current Session).
In the Observations Viewer, if we were interested in statistical data of observations (Viewing Observations → Statistics), the number of Inner Sanctum was always 0 (zero) – it was counted wrongly, in fact that is not counted.
The new version of Pleione can be downloaded from here.

I am still waiting for comments and bug reports. Please send it to the csukas.matyas@gmail.com e-mail address.
