The summary photometry contains global magnitudes and errors for each filter, positions, and a single flag that incorporates several different data quality measurements. The raw HSTPHOT photometry output contains the global data quality measurements, both global photometry and photometry from separate pointings, and has data quality measurements individually for each filter and for each separate pointing.

Relative aperture corrections between the chips for m32_u28807 appear to be outliers from the relation defined by the ensemble of all of the fields in the database. This may indicated possible problems with the aperture corrections, which would lead to zeropoint errors in magnitudes and colors. You should inspect the detailed photometry intrormation for this field, and be aware and cautious of the possibility of zeropoint errors. Users are advised to inspect the photometry diagnostics for this (and all) fields
