Yikes, something wrong happened.  Applying the correction should not have made
things worse, which the results imply.  More likely there was a problem running
skippy.  From now on, when reporting skippy results, can you please include the
list of matched star pairs and their residuals (the output immediately preceding
the "THETAF" output).  This is the only QA available, and the only way we have
of knowing whether the results are meaningful or not.
Do you run skippy within some standard directory?  That is, I'd like to modify
skippy so that it sends its results to a file as well as the screen, so that we
can try and figure out what happened later if necessary.  I could add an
argument specifying the directory to send the results to.  What default value
should I use (the log file directory??).
