Thanks, @eteq. You have 3 backticks after cfit instead of two.

This is a code-wise trivial but conceptually important clarification that qfit and cfit are similar to "chi" and "sharp" as used in DAOPHOT. Of course it already mentions the hst1pass connection, but a lot of people I know who do crowded field stellar photometry are more familiar with the DAOPHOT and DOLPHOT terminology, so it seems useful to add that connection as well.
