AstroDiff image is not as expected #500

Open liorozer opened 2 months ago

liorozer commented 2 months ago

The difference Image is not as expected, by Eran. Could be a problem with the SigmaN, SigmaR values.

To observe run the following code (make sure marvin path is correct for you): AInPath = '/marvin/LAST.01.04.03/2023/09/13/proc/195156v0/LAST.01.04.03..clear_000_001_009_sci_coadd_Image_1.fits' AIrPath = '/marvin/LAST.01.04.03/2023/09/16/proc/181015v0/LAST.01.04.03..clear_000_001_009_sci_coadd_Image_1.fits' AIn_Dir = '/marvin/LAST.01.04.03/2023/09/13/proc/195156v0' AIr_Dir ='/marvin/LAST.01.04.03/2023/09/16/proc/181015v0'

FN = FileNames.generateFromFileName(AIn_Path); AIn = AstroImage.readFileNamesObj(FN,'Path',AIn_Dir); FR = FileNames.generateFromFileName(AIr_Path); AIr = AstroImage.readFileNamesObj(FR,'Path',AIr_Dir);

AD = AstroZOGY; AD.Ref = AIr; AD.New = AIn;

AD.register; AD.subtractionD; AD.subtractionS;

I suspect the problem is due to an erroneous value for SignaN/SigmaR - check
