    3939== dvoRegionID ==
     40
     41It appears that the REAL/-999 version is more correct?
    4042
    4143{{{
     
    5153
    5254== ForcedWarpExtended ==
     55
     56Should these be transitions to Janskies?
    5357
    5458{{{
     
    6872
    6973== ImageMeta.nx/ny ==
     74
     75Proposal: Drop these columns, as they are currently incorrectly population, they will be identical for all rows, and the confuse the number of detection column names.
     76
    7077{{{
    7178nx                       ImageMeta               pixels                          SMALLINT              -999      "Image dimension in x."
     
    7683
    7784== posImageID/negImageID ==
     85
     86I cannot find which columns these link to or reference.
     87
    7888{{{
    7989posImageID               DiffMeta                dimensionless                   BIGINT                  NA      "positive image identifier"
     
    8292
    8393== psfModelID ==
     94
     95Is the VARCHAR(100) version correct?
     96
    8497{{{
    8598psfModelID               ForcedWarpMeta          dimensionless                   VARCHAR(100)                    "PSF model identifier."
     
    89102
    90103== skyCellID ==
     104
     105Which version/default is correct?  Proposal: This column (skycellID), tessID, and projectionID should index a table like the GPC1.skycell table, which lists tessellation, skycell_id, ra, dec, l, b, and the width and height of the skycell on the sky.  This information is currently unavailable in PSPS, and would make skycellID more useful.
     106
    91107{{{
    92108skyCellID                DiffDetection           dimensionless                   REAL                  -999      "Skycell region identifier."
     
    102118
    103119== ForcedMeanObject/DiffDetections/ForcedWarpMeasurement.Xflags ==
     120
     121Can these all be converted to INT/0 columns?
     122
    104123{{{
    105124gFlags                   ForcedMeanObject        dimensionless                   BIGINT                  NA      "Information flag bitmask indicating details of the photometry from forced single epoch g filter detections.  Values listed in ObjectInfoFlags."
     
    128147
    129148== Qf/Cf ==
     149
     150These seem inconsistent.  After asking Gene, he claims that no Cf parameters will be measured (and are scheduled to be dropped from the schema), so all coverage factors in PSPS will be Qf.
     151
    130152{{{
    131153gpetCf                   StackPetrosian          dimensionless                   REAL                  -999      "Petrosian (1976) fit coverage factor for g filter stack detection."
     
    144166
    145167== ra/dec ==
     168
     169Values seem to be consistently FLOAT, errors are consistently REAL, but the defaults are not consistent.  Are these correct as is, or should the defaults be different?

    146171{{{
    147172dec                      Detection               degrees                         FLOAT                   NA      "Declination."
