Changeset 19532 for trunk/psModules/src/imcombine/pmStack.h

Message:

Correcting stack variances for the imperfect convolution. Changed (again) the way the deviations are calculated; they're now straight chi^{2, which allows us to estimate how the variance factor needs to be changed in order to correct for it. Moving additional values into pmSubtractionKernels so that this can be calculated from a kernel that has been read in (very useful for debugging, also nice to have a record of the quality of the fit).}
