HISTORY Notes by Steve Snowden (21/09/93):
HISTORY Created from all-sky survey data. Shifted templates were created
HISTORY from PSPC C data (pre 25-Jan-93) which were alligned with the window
HISTORY support structure of the PSPC B data (post 25-Jan-93). The shifted
HISTORY templates were then scaled by the PSPC B data. Time periods of
HISTORY enhanced noncosmic background have been removed and an estimate of
HISTORY the particle background has been subtracted.
