[daip] LPCAL Errors

[Francesca D'Arcangelo]

I'm having problems with LPCAL.  About a month ago, I ran it (after
running CCEDT) using the 31DEC04 version of AIPS, and it gave me this
message:  

agn.bu> LPCAL1: Task LPCAL  (release of 31DEC06) begins
agn.bu> LPCAL1: Processing IF number    1
agn.bu> LPCAL1: ZCLOSE: LUN = 28 ALREADY CLOSED IN FTAB ON SEARCH
agn.bu> LPCAL1: LPCSEL: NO DATA SELECTED FOR IF   1
agn.bu> LPCAL1: Appears to have ended successfully

When the images and the exact parameters were tried on another computer,
LPCAL ran fine, with no errors.  

This month, I reinstalled AIPS, the 31DEC06 version, and am still
getting the same errors with LPCAL.  Do you have any idea what could be
wrong?  As I said, the parameters and images work on another computer
(running LPCAL) fine.

FYI, an example of the parameters I'm using is:
(I only change CALSOUR, IN2NAME, IN2CLASS, and NCOMP.)

Thanks for any help you can give me!
