HISTORY Mapping of Galactic l,b to X,Y pixels for the
HISTORY Wisconsin soft X-ray maps.
HISTORY Aitoff projection: centered on (l,b) = (180,0)
HISTORY First plane is X, second is Y.
HISTORY Lookup table for the FITS version of the Wisconsin Survey of the
HISTORY Soft X-Ray Diffuse Background (McCammon et al. 1983, ApJ, 269, 107).
HISTORY Values of -999. indicate regions outside the range of
HISTORY the projections.
HISTORY Documentation for the survey is available online from the
