Beginning of ReadMe : II/207A Palomar-Green catalog UV-excess stellar objects (Green+ 1986) ================================================================================ The Palomar-Green catalog of ultraviolet-excess stellar objects. Green R.F., Schmidt M., Liebert J. <Astrophys. J. Suppl. Ser. 61, 305 (1986)> =1986ApJS...61..305G ================================================================================ ADC_Keywords: Ultraviolet ; Photometry, UBV ; Photometry, uvby ; Blue objects Keywords: photometry - quasars - stars: faint blue - stars: spectral classification - stars: stellar statistics - stars: subdwarfs - stars: white dwarfs 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.
