Exercise 3: Slide 27. Using Subsets Of Detectors

After you have found a good fit using all 3 detectors, try omitting in turn each of the NaIs, then the BGO. Do this by clicking 'Redo last fit' and clicking the name of the file you wish to omit in the selection window that pops up. Try adding another detector or two (n9, n8, or even b0). Test the effect on the parameters and their errors, and play with the Effective Area correction addition to the model fits.
