Abstract

Radiation transfer theory has been used recently to derive the source function of the soft X-ray diffuse background, resulting in the claim of evidence for 10⁶ K gas in the Galactic halo. We show that this analysis has several errors that invalidate its conclusions. We argue that the case for an extensive hot (10⁶ K) halo remains open pending further work but may well be settled by the continuing series of ROSAT observations of high-latitude soft X-ray shadows.
