摘要：

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 10(6) 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 (10(6)' 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.
