Abstract (from CDS):

We present a summary of spectroscopic identifications of bright soft high galactic latitude X-ray sources from the ROSAT All-Sky Survey with total PSPC count rates 0.11<CR<0.5cts/s and hardness ratios HR1<0. This study supplements the identification program of a complete sample of sources with CR≥0.5cts/s presented previously. 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°, Seyfert galaxies dominate, whereas at intermediate latitudes galactic objects as magnetic cataclysmic variables and white dwarfs become relatively more frequent.
