[KIDS] QC coadds for KiDS-INT-DR2

[Gijs Verdoes Kleijn]

Dear COADD-QC-TEAM, dear Nicola as lead of QC catalog team.

We have the following QC checks in place:

  *
    DONE: visual inspection (using QualityWISE), to identify processing
    issues
  *
    DONE?/EMH: PSF difference between CoaddedRegriddedFrame and input
    ReducedScienceFrames: see verify method in RegriddedFrame.py
    <http://www.astro-wise.org/viewvc/awe/astro/main/RegriddedFrame.py?view=markup&sortby=file&sortdir=down>
  *
    DONE: consistency check on input RegriddedFrames

These are either in the general verify method for CoaddedRegriddedFrames 
in RegriddedFrame.py 
<http://www.astro-wise.org/viewvc/awe/astro/main/RegriddedFrame.py?view=markup&sortby=file&sortdir=down> 
or the KiDS-INT-DR2 specific code: qcCoadd_INTDR2.py 
<http://www.astro-wise.org/viewvc/awe/astro/experimental/kids/qcCoadd_INTDR2.py?view=markup&sortby=date>

I propose as next step deciding which additional checks are needed for 
KiDS-INT-DR2 at coadd level:
  * AG+GVK+team: completion of QC coadd checks, using QC criteria coadd 
<http://wiki.astro-wise.org/projects:kids:survey_task_teams:coadds#quality_criteria_for_coaddedregriddedframes> 
as starting point.

For this we need to define the scope of QC coadd: where does QC coadd 
end and QC catalog begin. I think a clear division is to leave to QC 
catalog team als those QC checks that can only be done well with good 
catalogs. So also those that check rather the coadd quality then catalog 
quality. QC coadd lead Lino + Gijs can be liaison to QC catalog team to 
help the QC catalog team in those cases.

What does QC coadd team deliver for KiDS-INT-DR2?:
My proposal:
1.the QualityWISE page: those we have in hand, they come for free with 
Astro-WISE coadd production. Input on improving the plots presented 
there is welcome.
2. A set of additional plots and/or numbers per coadd that complements 
the QualityWISE page with KiDS-INT-DR2 specific stuff. This can be 
either presented as one page per coadd or gallery of a certain plot for 
the 52 coadds. Danny is looking into this. I see this set as an 
experiment from which we can choose how to develop QualityWISE further 
after KiDS team meeting in December.

Discussion has opened: all input welcomed (keep emailing 
kids at astro-wise.org!)
