This wiki page will record information gleaned from the biweekly Monday SVA1 Analysis telecon.  In the end, this will build up a compilation of best-practices and systematics for different magnitudes; star/galaxy separation; photometric zeropoints; masking; etc.

Currently, "Bob Armstrong's SLR zeropoints":https://cdcvs.fnal.gov/redmine/projects/descalibration/wiki/Stellar_Locus_Regression have been tested and work reasonably well, but "finer scale SLR":https://cdcvs.fnal.gov/redmine/projects/descalibration/wiki/Stellar_Locus_Regression_for_SVA1_on_HEALPix_Grid is being worked on.

h2. Coadd catalogue objects provenance
155 19 Richard McMahon
156 19 Richard McMahon
Coadd catalogue provenance link to input catalogue files. It would be useful to have the source id from
157 19 Richard McMahon
the input catalog files
158 19 Richard McMahon
159 19 Richard McMahon
e.g.
160 19 Richard McMahon
161 19 Richard McMahon
DES0226-0416_r_cat.fits
162 19 Richard McMahon
163 19 Richard McMahon
TTYPE1  = 'NUMBER  '           / Running object number
164 19 Richard McMahon
165 19 Richard McMahon
This would allow joins between COADD_OBJECTS and OBJECTS_CURRENT and allow end-to-end checks.
166 19 Richard McMahon
167 35 Richard McMahon
OBJECTS_CURRENT has columns called:
168 35 Richard McMahon
169 35 Richard McMahon
OBJECT_ID,NUMBER,22,11,0,
170 35 Richard McMahon
OBJECT_NUMBER,NUMBER,22,6,0,
171 35 Richard McMahon
PARENTID,NUMBER,22,11,0,

173 45 Richard McMahon
174 45 Richard McMahon
h2. Coadd catalogue objects deblending information
175 45 Richard McMahon
176 45 Richard McMahon
It would be useful to know which objects are members of a blend so that one can
177 45 Richard McMahon
determine the magnitude difference and pairwise separattions so that the effect of
178 88 Peter Melchior
blending can be estimated.
