3 weeks ago In the new version (mextractor) we should do the following: after the PSF fitting: use X and Y to calculate SN_DELTA - i.e., FLUX_AT_X_Y/ANNULUS_STD
In addition, at the best fit position of each source we should fit (only the flux) using an extended version of the PSF - i.e., the PSF convolved with a predefined exponential function (extended sources). This will be called: SN_EXT1 and maybe SN_EXT2

So the question is whether a) to change the default behavior of imProc.calib.photometricZP to use SN_1 or SN (which is added to the source table any time we use PSF photometry, either single- or multi-iteration) instead of SN_2 or SN_3 or b) to change the Args.photometricZPArgs{:} argument within pipeline.generic.singleRaw2proc if multi-iteration PSF photometry with empirical PSF search is employed therein.
