-v1 : wrong value for gain and full well used
-v2 : rectifies wrong value for gain and full well, however discovered CR rejection also seems to blotch PSF core often leading to outliers, particularly in F775W (sharpest PSF)
-v3 : no CR rejection, also disables MAST phot scaling of UVIS2 counts to UVIS1, so this should be on the UVIS2 natural system

+From AC:
+
+The tables include measurement derived with Sextractor (labeled as “s”) and
+DAOPHOT (labeled as “d”).
+
+The number of measurements that I have for Cycle22 stars seems larger (976)
+than what is listed in Abi’s last catalog allmeasures_cy22_abi (635). But may
+be this is not the last version? The number of measurements for Cycle20 stars
+(108) agrees.
