background spectrum
Tool to create quiescent particle background
spectra. A1795, Model Particle Background, and
Filter Wheel Closed Spectra. The difference
between the observed and background spectra at
high energies is residual soft proton
contamination.

The quiescent particle background is significant
at higher energies even for bright and hard
sources. A1795 Spectrum
Fitted background subtracted spectrum
Same fit as above but without the background
subtracted from the data

• Background subtracted, exposure corrected, and
• Adaptively smoothed image of Abell 1795 in the
  0.35-1.25 keV band.

• Prototype mosaicking of Coma Cluster
  observations.
• The data have been background subtracted,
  exposure corrected, normalized between adjacent
  pointings, and adaptively smoothed.
