II/115A   Faint Blue Objects at High Galactic Latitude     (Warnock+ 1982-1990)

Faint Blue Objects at High Galactic Latitude. Catalog of Objects in SA 28, 29, 55, 57, 71, 82 and 94. Warnock III A., Usher P.D. <ADC Bull. 1, 195 (1982)>
ADC_Keywords: Blue objects; Stars, blue; Stars, faint; Stars, faint blue Description: The data set of Faint Blue Objects at High Galactic Latitude is a catalog of objects selected according to relative ultraviolet excess from ubv three-color 1.2-m Palomar Schmidt plates. Five selected area fields centered on SA28, SA29, SA55, SA57 and SA94 are included. The data consist of color classifications, B magnitudes, 1950 equatorial coordinates and remarks; the current file contains 3678 objects. Three selected area fields were included originally, centered on SA57 (Usher 1981), SA29 (Usher, Mattson and Warnock 1982) and SA28 (Usher and Mitchell 1982). Areas centered on SA55 and SA94 were added in 1984; areas centered on SA71 (Usher et al., Paper V, 1988ApJS...66....1U) and SA82 (Usher & Mitchell, Paper VI, 1990ApJS...74..885U) were added in 2007 by CDS.

Note on US: The sequential number corresponds to the Selected Areas (SA): SA57 (1-634), SA29 (635-1184), SA28 (1185-2363), SA55 (2364-3101), SA94 (3102-3678), SA71 (3679-3965), SA82 (3966-3987) Note on Color: Color class is based on the criteria: For U-V < 0: 1A = Above the blackbody (BB) line by δ(U-B) ≥ 0.15 mag; region populated mainly by quasars. 1 = Within δ(U-B) approx. ± 0.15 mag of BB line. 1B = Below BB line by δ(U-B) approx. 0.15 mag (in general vicinity of white dwarf cooling curve). 1BS = Close to the luminosity class III-V line for blue halo stars. For U-V ≥ 0: 1C = Above the BB line in the region where type N and continuous spectrum galaxies often located. 2 = Below the BB line, but not within the color class 3 region. 3 = Within the region of the subdwarfs and halo horizontal-branch stars. The class field can contain a colon (:) indicating uncertainty, an exclamation point (!) or a question mark (?). Note on Rem1: In the notes from original catalogs, the following abbreviations are employed: E = edge zone -- object within approx. 1 deg of plate edge G = galaxy, as determined from morphology plate CG = compact galaxy C = confused source Q = known quasar (from Veron and Veron 1974 and succeeding papers) ? = uncertainty R = remark in bytes 59 to 118
Remarks, Modifications, Acknowledgments and References: The Faint Blue Objects at High Galactic Latitude data file was received on magnetic tape from A. Warnock III on 2 April 1982. The only modifications made to the file were that the B magnitude field was converted to a blank field when no value is given (it was 0.0 when received) and the logical record length was changed from 132 bytes to 118 bytes, since bytes 119 to 132 were never used. Additional data for SA55 and SA94 were received in 1984 and were incorporated into the existing catalog in the same format. For a discussion of the methods employed in object selection, see Usher (1981ApJS...46..117U) and Warnock and Usher (1982). * 25-May-1995: Documentation by M.C. Larkin [SSDOO/ADC] and C.-H.
