*fit* -- Fit Data to a Specified Model

With PROS2.3 all fitting is performed using Poisson statistics, rather than Gaussian, so that results will be correct even for small counts () in some channels.

• Power Law fit to a Point Source
• Raymond Model
• Two-Temperature Raymond Model
• Limiting Energy Channels Input to the Fit
• Multiple Data Sets
• Verbose Mode
• Fit a source with a small number of net counts
• Inspection of results
