Description:
The Palomar-Green Catalogue of UV-excess stellar objects provides
positions accurate to about 8arcsec in each coordinate, photographic
B-magnitudes accurate to 0.29mag, spectral types, some
cross-references, and photoelectric broad-band, multichannel, and
Stroemgren colors when available.
Of the 1874 objects in the catalogue as published in 1986 (1878 in
this version), 1715 comprise a statistically complete sample covering
10714 square degrees from 266 fields taken on the Palomar 18-inch
Schmidt telescope. Limiting magnitudes vary from field to field,
ranging from 15.49 to 16.67. The overall completeness is estimated to
be 84%, but that figure and the relative contributions of magnitude,
color, and accidental errors vary depending on the magnitude and color
distribution of the spectroscopic subsample.
