Quid if you have many Variables in the image field of view. ************************************************************** 1) Create sequences ======================= If you have two or more variables (SS Cyg, SS Cyg1, ASASxxx) in your images SSCyg-V-xxxx.fits, you create for each variable a different sequence. Each variable will have a different "VariableTableIndex" e.g. SSCyg SSCyg1 ASASxxx 2) Create a text file SSCygFOV.txt ================================== This file will describe the variables in the Field of View and will contain the following lines /im SSCyg /vi SSCyg1 /vi ASASxxx and save it the directory your WHERE LesvePhotometry database is stored. Where /im SSCyg /im is a separator followed by the first part of the image names (e.g. SSCyg#2019-xx-30C 30sec.fits) which is used as the first VariableTableIndex /vi SSCyg1 /vi ASASxxx /vi is a separator followed by the VariableTableIndex of SSCyg1 star and ASASxxx star 3) Create a batch file SSCygFOV.bat =================================== Which will contain two lines: cd "C:\Program Files (x86)\Common Files\DPP Lesve\LesvePhotometry" LesvePhotometry.exe C:\_AstroImages\2019-10-02 /txt SSCygFOV.txt The first line defines the directory where the LesvePhotometry program is located. The second line is the command line launching LesvePhotometry and the parameters are : C:\_AstroImages\2019-10-02 is the directory containing your images /txt SSCygFOV.txt refers to the file describing the variables 4) Launch the batch file ======================== Double click on the batch file name to launch it or right click and choose "Run as administrator" .
