I. Appenzeller et al., IDENTIFICATION OF A COMPLETE SAMPLE OF NORTHERN ROSAT ALL-SKY SURVEY X-RAY SOURCES - III - THE CATALOG, The Astrophysical journal. Supplement series, 117(2), 1998, pp. 319-340
We present a catalog of optical identifications of a representative sa
mple of northern (delta > -9 degrees) ROSAT All-Sky Survey (RASS) sour
ces. A full identification has been carried out for a count-rate- and
area-limited complete RASS subsample comprising 674 sources. All sourc
es are within six study areas outside the Galactic plane (\b\ > 19.deg
rees 6), one area being near the north Galactic pole and one near the
north ecliptic pole.
