What Forward Fitting Does

The intent of the Forward Fitting method is to determine the best fit to the data of a Gaussian model. (This may be extended to more complicated functions than Gaussians.) The method goes like this:
  1. Make a back projection map.
  2. Find the location of the brightest source.
  3. Define a model Gaussian (or other basis function) at that point.
  4. Compute the modulation profile from the model.
  5. Compare with observed count profiles, modify model and repeat.
  6. Stop when the modulation profile is adequately fitted.
  7. If additional sources exist, subtract the current model, go to 2.
