Is 'mosxx' a valid keyword?  (As in 'fit mosxx 10 to 250')  I don't see
it in the manual, but I may have missed something.  Warnings about
keywords are printed at the top so it's easy to miss them, and if it
ends up not refining mosaicity, it could mess things up a bit. 

Then again, maybe it is a valid keyword after all....

Mistakes in definition of image ranges cause random error messages to
spring up all over the place.

Oh, wait a minute:  you're not fitting beta*.  That is bound to mess
things up. 

phx.
