Soft X-ray Diffuse Background: ROSAT 0.75 keV All-Sky Map
3/4 keV diffuse background map from the ROSAT all-sky survey in the
same
projection as Figure 1. The image shows a radically different structure
than
the 1/4 keV background of Figure 1. At 3/4 keV, the sky is dominated by
the
relatively smooth extragalactic background and a limited number of
bright
extended Galactic objects.
