      Description

      Identify a visit in the ap_verify HiTS 2015 dataset with the 2014B coadds by Ian Sullivan (/project/sullivan/hits2014B/cwcoadds_processed2/) that has the sharpest science image compared to the template.

       

      The goal in this ticket is to check whether the science image convolution fails because the AL solution has known problems in close matching PSF cases (when PSF FWHM difference is < about 1px).

            Visit 411355 was identified as a non-"close match" case (FWHM 4.99 px -> 3.27 px in imgD_411355_2019-10-01.log). There wasn't any noticeable difference in the number of detected sources.

            Could you please have a look at this ticket ? It's comment only and the goal is to close it perhaps at the sprint planning.
