    v5 v6  
    44  * Detection table references !DetectionCalib and !DetectionFull tables, which do not appear to exist. 
    55   * Typos in table description: "unless one wantw to do the our the astrometric".
     6   * Are the FWHM values really in arcseconds?
    67  * No description text for !DiffDetObject table.
    78  * No description text for !DiffDetection table.
     
    1213   * gFPSFFlux and other filters has confusing Description text.
    1314  * No table descriptions for !DiffMeta, !DiffToImage, !ForcedMeanLensing, !ForcedMeanObject, !ForcedWarpMeasurement.
    14    * Is
     15   * Are the FWHM values really in arcseconds?
    1516  * !MeanObject table has no table information.  Unclear table description.  Quadruple-quote typos.
    1617  * !ObjectThin has confusing table description. 
     
    4041   * gxPos/gyPos/other filters claim to be in arcseconds, but a query suggests it is in pixels (or "stack pixels" to keep consistent with ForcedWarpMeasurement/Detection)
    4142   * gxPosErr/gyPosErr/other filters also claims to be in arcseconds.  The query again suggests pixels.
    42    * gpsfMajorFWHM/gpsfMinorFWHM claims to be in arcseconds as well.  I suspect this to be in pixels as well.
    43    * gmomentXX/XY/YY/R1/RH claim to be in units arcsec squared/arcsec squared/arcsec/sqrt arcsec.  This is inconsistent with Detection and ForcedWarpMeasurement, which list all five in units of pixels.  I
     43   * gpsfMajorFWHM/gpsfMinorFWHM claims to be in arcseconds as well.  I suspect this to be in pixels as well.  This point is more thorough than those for Detection and ForcedWarpMeasurement because I didn't notice any issues until going back to check from here.
     44   * gmomentXX/XY/YY/R1/RH claim to be in units arcsec squared/arcsec squared/arcsec/sqrt arcsec.  This is inconsistent with Detection and ForcedWarpMeasurement, which list all five in units of pixels.
     45   * gapFillFac/gexpTime/filters is unclear.
     46   * gsky/filters is unclear in units between description and units.
     47  * !StackObjectThin has no table description.
     48   * randomStackObjID references a random objid that does not appear in this table.
     49   * stackDetectRowID/primaryDetection issue.
     50   * ginfoFlag/ginfoFlag2/ginfoFlag3/filters descriptions are unhelpful.
     51  * !StackPetrosian has no table description.
     52   * stackDetectRowID/primaryDetection issue.
     53   * gpetRadiusErr/filters largely all -999.
     54   * when gpetMag/filters = -999, the gpetR50/gpetR90 values and errors appear to be nonsense.
     55   * gpetCf/filters has values greater than 1.  This is listed as units of pixels, but a I was expecting a coverage factor to be a 0-1 like Detection.psfQf.
     56  * !ImageFlags looks correct.
     57  * !CameraConfig has an unhelpful description.
     58  * !DetectionFlags suggests that it is only applicable to the Detection table.
     59  * I am assuming that all *ObjectView tables pull their row description information from the tables that comprise the view, and will not re-examine those.
     60  * Filter has an unhelpful description.
     61  * !ForcedWarpExtended  has no table description.
     62   * skyCellID has a typo in the description.
     63   * flxR5/radii should have radius units in the description.
     64   * obsTime description references "positive detection" which is all that exists for a forced warp measurement.
     65  * !ForcedWarpLensing has no table description.
     66   * skyCellID/obsTime as before.
     67  * !ForcedWarpMeta has no table description.
     68   * This table is also the first place I've seen an "alphanumeric" unit, which have been simply "dimensionless" in other tables when a similar field was a string (qv DetectionFlags).
     69  * !ForcedWarpToImage has no table description.
     70  * !FrameMeta has typos in the table description.
     71   * p1Recip/p2Recip/p3Recip do not appear to be populated.
     72   * expStart is in "days".  Previous entries for similar time fields have used Mean Julian Days.
     73   * ctype2 has no unit description, neither alphanumeric nor dimensionless.
     74   * crpix1 has "pc001001" as the units, which is a header keyword.  crpix2 has units "dimensionless" which doesn't seem right either although it does match other uses (DiffMeta).
     75  * !ImageMeta.
     76   * imageID has undefined reference to ALEX.
     77   * I am suspicious that the bias and biasScat values are identical for all OTAs in an exposure.
     78   * magSat and completMag do not appear to be populated (values=0, not the default value of -999).
     79   * nx/ny are incorrect, or at best incomplete.  They list values = (590, 598) which is the size of a single cell, not the full OTA that this table is describing.  Are these useful at all given that they will be identical for every exposure?
     80   * A similar question about psfModelID (=-999).
     81   * My continuing confusion on FWHM units.  These again have values (~4) that make me suspect they are actually in pixels.  Similarly for psfWidMajor, psfWidMinor.
     82   * momentM2C/M2S/M3/M4 units.  These are all pixels for the Detection table.
     83   * detrend1-8.  If these are pulling specific header values (which they appear should be), then the descriptions should be updated to reflect which detrend they are mapping.  In addition, DETREND.NOISEMAP, DETREND.NONLIN, DETREND.VIDEODARK, and if it's not already included DETREND.FRINGE should be included.  Pulling PTRN_ROW and PTRN_CON (booleans) might also be useful.
     84   * crpix1/2 have units of pixels here, and so FrameMeta should be changed to match.
     85  * !ObjectFilterFlags has an unclear table description.
     86  * !ObjectInfoFlags has an unclear table description.
     87  * !ObjectQualityFlags has an unclear table description.
     88  * !PhotoCal references a DetectionCalib table that does not exist.
     89  * !StackDetectionFlags references a StackDetection table that does not exist.
     90  * !StackMeta magSat does not appear to be populated.
     91   * expTime references the units in the description.
     92   * completMag,astroScat,photScat,nAstroRef,nPhoRef, photoColor do not appear to be populated.
     93   * crpix1/2 have units dimensionless.
     94   * psfFwhm_mean/_max units.
     95  * TessellationType does not have a table description.
