      Description

      Some (but not all) images from the AuxTel imaging survey to do not pass characterizeImage. This work is to classify and characterize these failures and explore configuration settings to improve the success rate.

            Collected errors from BPS run collection - 'u/edennihy/sqrDegSurvey_bpstest1' on imaging survey frames. At least four different classes of errors:

            Failure Type Example Images Potential Solution
            Exception IndexError: No viable PSF candidates survive 20211102 -> 223,229, 241  
            Exception RuntimeError: No objects passed our cuts for consideration as psf stars 20211102 -> 238, 249, 255  
            Exception RuntimeError: No usable PSF candidates supplied 20211102 -> 225, 231, 259  
            Exception RuntimeError: Unable to measure aperture correction for required algorithm 'base_GaussianFlux': only 1 sources, but require at least 2. 20211102 -> 221, 222, 224 turn off app corrections (charImage.doApCorr = False)

            These issues were determined to be primarily the result of extremely sparse fields (n_src < 5), not a result of poor task configuration. Marking ticket as Done.
