_______________________________________________________
Details:
Due to some typo during the re-write of MakeCatalog, it is mistakenly
subtracting the total river flux (around each clump) from the total clump
flux! But this is wrong!!! It should be like this: the total clump flux should
be divided by the mean river flux, multiplied by the number of clump pixels.
This resulted in negative S/N values in some situations.
This bug was found by Joseph Putko.
