Abstract

The data from a recently completed survey of the galactic plane with the SAS-3 modulation collimators provide precise (20″-60″) celestial positions of galactic X-ray sources. Preliminary positions of 60″ precision are reported for five sources. One of these led to the identification of the star, γ Cas, as an X-ray source, and the others lend substantial confidence to previously proposed optical identifications: 3U0352 + 30 = X Per, 3U1145 61 =HEN 715, GX301 - 2 = WRA977, and GX304 1 = star. These identifications seem to establish the existence of a previously suggested class of De-star X-ray emitters.
