AST results in the F475W and F814W HST WFC3 passbands. Panels a and b: grey dots show the sharpness of the AST stars; filled (star-like objects) and open (extended objects) circles show the sharpness of the real measured objects. Panels c and d: grey dots indicate the difference of recovered and input magnitudes of the AST stars; black lines indicate average photometric errors provided by DOLPHOT for real objects. Results in panels a–d are shown vs. recovered and measured magnitudes. Derived photometry completeness estimates in the F475W and F814W passbands are shown in panels e and f vs. input magnitudes, respectively.
