Ted et All,

        That would be great if you could look into the problem of
calculating RA & Dec in the wide-field enviornemnt that the Mark IV image(s)
are taken in. Hopefully we will have some way of "checking in/out
 source code between now and the end of the year..

    Herb and others that have been writing analysis code should be able to
use this type of a system as well to "store" thier code for future use by
others that may be interested....
