+ObjectThin
+    No fluxes or magnitudes
+
+Detection
+    Fluxes are in adu / sec
+    Also: KronRadius and apRadius both appear to be in pixels. The schema browser page says
+    that KronRadius is in pixels but apRadious is in arcsec
+
+    Similarly the fwhm values look to be in pixels schema says arcsec.
+
+
+StackObjectThin
+    Has magnitudes not fluxes.

+StackObjectAttributes
+
+  The following are in adu/sec
+    xPSFFlux
+    xKronFlux
+    xApFlux
+
+
+StackPetrosian
+    schema browser says units for xpetMag is Jy but the Description calls the column "PetrosianFlux"
+    The values show that it has been converted to a Pogson magnitude.
+
+StackApFlx (and the GalCon6 and GalCon8 versions)
+    Flux columns have been converted to Jy
+
+StackModelFit tables
+    Has magnitudes not fluxes.
+    Are the radii in pixels or arcsec? Sersic radius appears to be arcsec. Check.
+    Also the Sersic index looks funny. values are 0 to 1. Should be 0 to 4 or so.
+
+ForcedWarpMeasurement
+    Fluxes are in Jy
+
+ForcedMeanObject
+    Fluxes are in Jy Schema browser units are ABmagnitude Description says things like "robust mean g psf AB magnitude ..."
+
+    the various FluxStd columns (stdev?) look like they are in ADU based on the range of values.
+
+DiffDetection
+    Fluxes are in adu
