Back up.

This may duplicate entries on the other lists. I have not checked for duplicates yet (I will strike through the entry here when I do so).

Schema Browser

• Detection table references DetectionCalib and DetectionFull tables, which do not appear to exist.
  • Typos in table description: "unless one wantw to do the our the astrometric".
  • Are the FWHM values really in arcseconds?
• No description text for DiffDetObject table.
• No description text for DiffDetection table.
• DiffDetection uses "pixels" and "raw pixels". This seems like an error. "raw pixels" seems to be the standard on other tables.
• Should DiffMeta/DiffToImage be listed in "Fundamental IPP Data Products" or "Observational Metadata and Supporting System MetaData Tables"?
• ForcedMeanObject lists gFPSFFluxStd, gFKronFluxStd, gFApFluxStd, etc for other filters as dimensionless. These should be set to the correct flux unit to match the gFPSFFlux/gFPSFFluxErr values.
  • gFPSFFlux/gFPSFFluxErr claim to be AB magnitudes. They are fluxes, and therefore should not be in magnitudes. A database query suggests they are in Janskies.
  • gFPSFFlux and other filters has confusing Description text.
• No table descriptions for DiffMeta, DiffToImage, ForcedMeanLensing, ForcedMeanObject, ForcedWarpMeasurement.
  • Are the FWHM values really in arcseconds?
• MeanObject table has no table information. Unclear table description. Quadruple-quote typos.
  • Column orderings are different between g and other filters. gMeanPSFMagNpt comes after MagMin/MagMax, but r-y have this before.
• ObjectThin has confusing table description.
  • I do not think the objName is being calculated correctly. For example objID = 101273355750459367, (raMean, decMean) are (335.57505452, -5.60085831). This should convert to sexagesimal as (22:22:18, -5:36:03), which does not match the given name of "PS1.2 J222218.0--62356.9". I'm not sure if this is generically true, or simply a mishandling of negative declination.
    • Is this even the correct format? No. From Gene, these should be decimal.
  • objName description in DiffDetObject should probably match the version found here.
  • consistencyFlag does not appear populated.
  • nStackObjectRows does not appear to be populated.
  • nStackDetections does not appear to be correct. Example objID =101683338006825170.
  • nDetections seems wrong as well. objID = 101683337908223873
  • Unclear cx,cy,cz,lambda,beta,l,b descriptions.
  • ra/decErr occasionally -999, which doesn't not seem correct. Example objID = 101283355856926633.
• StackApFlx table description does not state the convolved FWHM values.
  • primaryDetection description is unhelpful.
  • gflxR5 and other radii and filters: can this list the radius in physical units as well?
• !StackApFlxExGalCon6 has no table description.
  • stackDetectRowID has typo in description. Is this a bitmask? A query to the database indicates this value is unpopulated with values -999.
  • primaryDetection description is unhelpful.
  • gc6flxR3 and other radii/filters: what are the radius units?
• !StackApFlxExGalCon8 has the same issues as !StackApFlxExGalCon6.
• !StackModelFitDeV has no table description.
  • stackDetectRowID complaint.
  • primaryDetection description is unhelpful.
  • DeVaucouleurs inconsistently spelled.
• StackModelFitExp has no table description.
  • stackDetectRowID/primaryDetection issue.
  • Exponential likely not needed capitalized in row descriptions.
• StackModelFitExtra has no table description.
  • stackDetectRowID/primaryDetection issue.
  • glogC/other filters description does not close parentheses.
• StackModelFitSer has no table description.
  • stackDetectRowID/primaryDetection issue.
• StackModelFitPet gpetCf is in pixels, and is dimensionless in other tables (see serCf in StackModelFitSer)
• StackObjectAttributes has no table description.
  • stackDetectRowID/primaryDetection issue.
  • 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)
  • gxPosErr/gyPosErr/other filters also claims to be in arcseconds. The query again suggests pixels.
  • 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.
  • 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.
  • gapFillFac/gexpTime/filters is unclear.
  • gsky/filters is unclear in units between description and units.
• StackObjectThin has no table description.
  • randomStackObjID references a random objid that does not appear in this table.
  • stackDetectRowID/primaryDetection issue.
  • ginfoFlag/ginfoFlag2/ginfoFlag3/filters descriptions are unhelpful.
  • Why is this table StackObjectThin when it contains more information than the ObjectThin table? Is there a definition of a Thin table?
• StackPetrosian has no table description.
  • stackDetectRowID/primaryDetection issue.
  • gpetRadiusErr/filters largely all -999.
  • when gpetMag/filters = -999, the gpetR50/gpetR90 values and errors appear to be nonsense.
  • 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.
• ImageFlags looks correct.
• CameraConfig has an unhelpful description.
• DetectionFlags suggests that it is only applicable to the Detection table.
• 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.
• Filter has an unhelpful description.
• ForcedWarpExtended has no table description.
  • skyCellID has a typo in the description.
  • flxR5/radii should have radius units in the description.
  • obsTime description references "positive detection" which is all that exists for a forced warp measurement.
• ForcedWarpLensing has no table description.
  • skyCellID/obsTime as before.
• ForcedWarpMeta has no table description.
  • 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).
• ForcedWarpToImage has no table description.
• FrameMeta has typos in the table description.
  • ~p1Recip/p2Recip/p3Recip do not appear to be populated.~
  • expStart is in "days". Previous entries for similar time fields have used Mean Julian Days.
  • ctype2 has no unit description, neither alphanumeric nor dimensionless.
  • 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).
  • telescopeID does not reference a table.
• ImageMeta.
  • imageID has undefined reference to ALEX.
  • I am suspicious that the bias and biasScat values are identical for all OTAs in an exposure.
  • magSat and completMag do not appear to be populated (values=0, not the default value of -999).
  • 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?
  • A similar question about psfModelID (=-999).
  • My continuing confusion on FWHM units. These again have values (~4) that make me suspect they are actually in pixels. Similarly for psfWidMajor, psfWidMinor.
  • momentM2C/M2S/M3/M4 units. These are all pixels for the Detection table.
  • 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.
  • crpix1/2 have units of pixels here, and so FrameMeta should be changed to match.
  • psfModelID is a string in StackMeta/ForcedWarpMeta.
• ObjectFilterFlags has an unclear table description.
• ObjectInfoFlags has an unclear table description.
• ObjectQualityFlags has an unclear table description.
• PhotoCal references a DetectionCalib table that does not exist.
• StackDetectionFlags references a StackDetection table that does not exist.
• StackMeta ~magSat does not appear to be populated.~
  • expTime references the units in the description.
  • completMag,astroScat,photScat,nAstroRef,~nPhoRef~, photoColor do not appear to be populated.
  • crpix1/2 have units dimensionless.
  • psfFwhm_mean/_max units.
• TessellationType does not have a table description.
• Should nAstroRef and nPhoRef be changed to match the usage in ImageMeta, ie numAstroRef/numPhotoRef?

General issues.

• All tables seem to have columns like "randomStackObjID" that contain a random value between zero and one. These are not ID fields in any sense.
