Discussion on the flux initialization in multiband data

2

It turns out that the flux initialization has quite an influence on the photometric result when running SE++ on mulit-band data. As an example I am using a simulated dataset...

I ran SE++ with sersic fitting on simulated images with sersic profile (in the context of the Euclid Morphology Challenge). When plotting the difference between two SE++ parameters pixel_centroid_x/y and...

**After the Jan.2020 release** The property does not use the variance vaues for the error estimate, but a derived Poisson noise value. Also, the property retrieves error values, but the...

**For after the Jan.2020 release!** The property contains for each detection pixel of a source: - the background subtracted pixel; - the filtered background subtracted pixel; - the filtered variance...

Here is the code that produces the base code for a new SourceXtractor++ Plugin: https://gitlab.euclid-sgs.uk/mkuemmel/mer_auxstuff/tree/develop/SourceXtractorPlugin That might be of general interest and could be included into SourceXtractor++.

In https://github.com/astrorama/SourceXtractorPlusPlus/discussions/575#discussioncomment-9011672 a user asked whether it is possible to have aperture photometry and auto photometry in the no-detection mode. We discussed it this morning. auto photometry is a no...
