Description:
File table1.dat contains the STIS near-UV photometry for the hot stars
in the core of M32. The catalog includes 8021 stars, and gives
position in the STIS image, magnitude, error, region of the image, RA
(J2000), and Dec (J2000). The photometry was performed in six distinct
regions of the image because of changes in the point spread function
across the image. Note that the relative astrometry is quite accurate
(tenths of a 0.025 arcsec STIS pixel), but the absolute astrometry is
subject to a 1-2 arcsec uncertainty (associated with the position of
the guide stars). Three stars were marked with a footnote in the
published catalog, because they are associated with planetary nebulae
in our field; they are at the following positions (x,y): (354.949,
821.325), (717.148, 669.210), and (994.924, 355.956).
