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:
- Make a back projection map.
- Find the location of the brightest source.
- Define a model Gaussian (or other basis function) at that point.
- Compute the modulation profile from the model.
- Compare with observed count profiles, modify model and repeat.
- Stop when the modulation profile is adequately fitted.
- If additional sources exist, subtract the current model, go to 2.
