I cannot see from the code how the history file could invent some
values other than those entered.  It does convert the dx, dy into DX,
DY in apparent coordinates to do the actual correction.  but the
BPARM(5,6) go unaltered to the HI file.  May I suggest that the line
you are seeing from the HI file is an older execution of CLCOR that is
copied around when new files are created?  That would explain the same
values appearing more than once.

On a happier response, Leonia with my help has replaced the fancy,
incomprehensible, and non-functional elevation code in UVFLG with a
straightworward routine that is not fancy but works.  At prsent it can
do only one subarray at a time and can do nothing but elevation in a
particular execution, if you need the elevation done.
