ROSAT All-Sky Survey: Soft High Galactic-Latitude X-Ray Sources 2

Listed in NASA Data Portal

This table contains a summary of spectroscopic identifications of bright soft high-galactic-latitude X-ray sources from the ROSAT All-Sky Survey (RASS) with total PSPC count rates 0.11 < CR < 0.5 cts/s and hardness ratios HR1 < 0.

Description

This study supplements the identification program of a complete sample of sources with CR >= 0.5 cts/s presented previously (Thomas et al. 1998, A&A, 335, 467; available at the HEASARC as the RASSHGSOFT table).

Spectroscopic identifications are presented for 70 of 77 sources, 5 sources are identified by other means, and subsidiary information is given for 2 as yet unidentified sources. In practically all cases, a unique optical counterpart exists. As for the brighter fraction of the sample, the largest source classes are Seyfert 1 galaxies, magnetic cataclysmic variables, and hot white dwarfs.

In the Galactic Pole caps at |b| > 40 degrees, Seyfert galaxies dominate, whereas at intermediate latitudes galactic objects as magnetic cataclysmic variables and white dwarfs become relatively more frequent. This table was created by the HEASARC in May 2012 based on <a href="cdsarc.cds.unistra.fr/ftp/cats/J/A+A/347/47">CDS Catalog J/A+A/347/47</a> file table3,dat. This is a service provided by NASA HEASARC .
