Introducing Vsp_Demo AIJ plugin ..
Vsp_Demo is a Java plugin I've developed to query the AAVSO Variable Star Plotter database, converting comparison star data into AstroImageJ radec-format aperture files. Radec files are useful for importing measurement apertures into plate-solved images.
Example work flow to use the plugin for WASP12 / V-filter / 60 arcmin fov:
1 User opens the plugin dialog and enters target, filter and field-of-view data.
2 Option: query Simbad catalog for target star RA / DEC coordinates
3 Run a query on VSP database, saving comparison star data in text file with filename format: <target>.<filter>.<fov>.radec.txt, e.g. WASP12.V.60.radec.txt
4 The software also queries the SkyView database and downloads a DSS fits file with similar filename format (e.g. WASP12.V.60.fits).
5 Open the WASP12.V.60.fits file in AIJ
6 Select WASP12.V.60.radec.txt from AIJ menu option Import apertures from RA/DEC list.
7 Option: select or deselect measurement apertures and save updated radec file
8 Run multi-aperture photometry analysis on a sequence of plate-solved images.
The current version is a prototype limited to queries of the VSP database. Later versions will enable the user to select comparison stars from the much larger AAVSO APASS catalog.
*** The plugin requires Java 8 (or later) runtime environment (jre8+) ***
AstroImageJ installation packages for Windows and Linux include Java 7 runtime environments. To run the plugin with current downloads, you will have to install Java 8 runtime (jre8) and configure AIJ to run with the later Java runtime environment.
Note: I understand from Karen that a new version of AstroImageJ is pending. The installation packages will include jre16 which addresses java compatibility issues.
Current version is Windows-compatible with a Linux version pending which I'll post on GitHub.
The plugin is hosted on GitHub repository:
Click on the User Guide link to download a user guide with instructions to install and run the plugin.
Click on the radec.zip link to download example fits and radec files, also described in the user guide.
Note: Option to run the radec.zip example files with current AIJ versions (java7) to see if this software might be useful (refer User Guide).
Aside from java version issues, software install and run instructions are quite straightforward and should take about 30 - 60 minutes on first run through. Please get back on this forum with any questions about installing or running the software. Thanks in advance for taking the time to try it out
