ROSAT Guest Observer Facility

If one wanted to use one band for an average representative exposure map, which band should one use?


If one absolutely wanted to do this, then probably one should use channels 42 to 131. However, even this is generally not a good idea, because the spectra of diffuse sources (and even of the diffuse background in various parts of the sky) can differ significantly from the sky-averaged background spectrum.
