Identification of a Complete Sample of Northern <i>ROSAT</i> All‐Sky Survey X‐Ray Sources. III. The Catalog

Abstract

We present a catalog of optical identifications of a representative sample of northern (δ > -9°) ROSAT All-Sky Survey (RASS) sources. A full identification has been carried out for a count-rate- and area-limited complete RASS subsample comprising 674 sources. All sources are within six study areas outside the Galactic plane (| b | > 196), one area being near the north Galactic pole and one near the north ecliptic pole.
