In the Source table (precursor schema) we currently keep 4 moments: do we need to go up to 4th moment? This adds a lot of columns to the largest table. Also we currently don't have errors for the moments, and we probably should - that is even more columns.

Tim will discuss this issue with the science collaborations. It seems likely that shape parameters such as moments will be needed in the Source table as well as the Object table, as the shape may change with time for various reasons (real Object shape changes, seeing variations, mis-association of Source to Object). It is possible that shape parameters beyond moments may be needed.
