ROSAT All-Sky Survey 3/4 keV

This image of the entire sky is from the ROSAT All-Sky Survey.
The survey was completed during the first 1/2 year (1990-91) of the ROSAT
Mission. The data, 0.75 keV, have been exposure corrected but not
cleaned of contamination. The strong striping of the data is an artifact
of the contamination and is caused by several processes. Solar X-rays
scattered by the residual atmosphere along the line of sight are a major
contributor. The image is an Aitoff-Hammer equal-area projection in
Galactic coordinates with the Galactic center at the center and longitude
increasing to the left.
