[daip] AIPS problem

Hello,
I am facing the following problem with AIPS:

I have been reducing 90cm continuum GMRT data with AIPS version 2003, on a
solaris 8 machine. That worked with no problems. Trying to get more speed,
I have installed the *binary* version of AIPS 2005 on a PC running
linux-fedora.
- I have saved the AIPS files on the solaris machine with FITTP
- I have loaded the AIPS files on the PC with FITLD
all seemed to work well, until I tried to generate a bandpass table on the
PC. It failed somehow, reporting thousands of excess closure errors and
generating a BP table that is full of NAN instead of the expected numbers,
such as 4.158633E-01... As far as I can tell,
the same AIPS fits file saved on the solaris machine, and read both on the
PC and the solaris machine again (just to check this is not due to the
saving procedure), with no further modifications, will result in BPASS
working fine in the solaris machine (AIPS 2003) but not on the PC (AIPS
2005). Many other tasks (on the PC) work well with the same file,
however...

could you help me pinpoint the problem? I think I will try to compile AIPS
on my PC machine from scratch, but if other tasks work well, I don't think
this will solve the problem.

thanks
Jose
