todo list of things for schema 20:

=== To add  or think about adding to schema 20 ===
 * galaxy shape parameters measured in forced warp are missing in schema
 * detection efficiency measurements
 * EG -> ExGal in table names '''done'''
 * drop skycell from DO '''done'''
 * is there a mean flux or something we can add to DO? it's a pretty useless table otherwise
 * DO had randomID not randomDiffObjID '''done'''
 * FO has no random number? '''done''' ''' needs to be added to ipptopsps'''
 * FO has ()stackID - drop it, it is meaningless '''done''' - fixed for ipptopsps as well
 * FW Lensing / FM Lensing need psf_E1,psf_E2 fields
 * change fullforce to use R3/R4/R5 similar to ST, actually, we should use R5/R6/R7 to match SDSS (this is a name change, SDSS R5 R6 R7 corresponds to stilts 3 4 5)
 * move sky to/from StackObjectThin/StackAttributes

=== views to fix ===

 * make a sensible view for Diffs
 * change view for Stack so there are no duplicates

=== To fix in ipptopsps or dvo (from sas37) ===
 * FO has no random number? add to ipptopsps '''done'''
 * Bundle FW by skycell
 * Bundle DF by skycell
 * make ipptopsps choose consistent duplicates (in stacks)
 * populate StackModelFitExtra


=== To fix in dvo ===
 * need bestDetection set for SAS38
 * populate qfperfmax in DO (it's grabbed from the dvo, it is not filled in the dvo)
 * ra/dec err in DO dvo is empty
 * FO gamma/ E1 /E2 are currently empty (filled from DVO, it is not filled in dvo)
