[aniello grado]

Dear Gijs,

sorry for the delay in the answer (very busy with the new VSTceN data
center and HW).

as a general comment I believe that the final QC on coadds and
catalogs comes from scientific requirements. With our partial QC we
can assess let say macro problems then we have to go a step deeper and
see what comes from the  main science goal that in case of KIDS is the
lensing. We could even discover that we have modify drastically the
way we process the data! So it is mandatory that a lensing analysis is
completed asap.

ok

Having a processing report automatically generated that resumes the
main info on the reduction can be very useful. The report should
contains a list of the images used (also for the calibrations), info
about global photometric and astrometric calibration plus a selection
of detailed info on the single exposures.
