All routines from filler.f down are identical to UGAP012.

Proper sequence is something like the following:

   piprog/piprog - looks at CCD parallax star list and makes
                   .ua files and does overlap.

   piprog/color0 - looks at .ua files and makes .ph files

   piphot/color1 - looks at .ph files and does fits as
                   well as putting all observations in a file.

   reverse/reverse - look up original cross revereces and makes
                     .xid file

   reverse/usexid - uses .xid files and makes .bok .ber .rok .rer
                    files.
