Observations of the Soft X-Ray Backgroundhat the intensity did not go to zero in the galactic plane where the absorption optical depth is very large demonstrated that they were at least partly galactic. In the last few years, several experiments have attempted to measure the X-ray shadows of the Small Magellanic Cloud, M31, and the Large M

Jenkins replied that the known irregularity in the distribution of coronal material makes a general interpretation from a single measurement untrustworthy, but the γ Cas measurement makes the notion that we are immersed in a coronal region less tenable.
