RE: Going, gone. Removed Sigma Squared.

[aah@nofs.navy.mil]

Chris wrote that he was removing sigma squared, but leaving mean ra and
ra sum of squares.  I don't see any problem with that.
  My question (yes, late, and I'm sorry) is why sum-of-squares is in deg^2.
You only use this field for calculating sigma later, and for that you use
the mean ra + nobs fields as well.  Since mean ra is in mas, then a unit
conversion needs to take place.
  Why not put sum-of-squares in mas so that everything is consistent?
