We need more detailed documentation for the GaussianCentroid algorithm, in terms of how it actually computes the centroid. We (Jim and Perry) have done what we can, but we need help from whoever actually wrote it (RHL, we think) to provide the rest. In particular:

• Additional detail should be filled in in the class Doxygen for GaussianCentroidAlgorithm, in GaussianCentroid.h
• The "noPeak" flag field description and name should be compared to what the algorithm actually does with it. It looks to me like it's a bit misnamed (and maybe shouldn't be considered an error condition at all, if we want to run this on difference images), but I'm not sure.
