[daip] CPASS bug

[Kristine Spekkens]

 Thanks.  In experimenting with CPASS I set CPARM(3) to be as small as
0.001 (recommended), with the same result I described.

 I've tried using BPASS as you suggest, and it works fine. Perhaps a line
in the help file for CPASS that warns against general use could be added?
It would be very helpful to relatively inexperienced AIPS users like
myself!
