Simon,

Is this using the "NRAO" version of ATLOD or the ATNF version???

Cheers
Chris

Subject: Problems with ATLOD after reference frame changes in AIPS

Dear LBAers,

Most of you would have seen the emails from Eric Greisen and Craig
Walker about the changes in the AN table format and geometry
introduced into AIPS a month or two back. After running the midnight
job on my 31DEC09 distribution late last week I found that I could no
longer load LBA data into AIPS using ATLOD (it crashes as shown
below). I was able to rollback my AIPS distribution a few weeks to
prior to the reference frame changes and ATLOD now works again as
expected.

I have emailed Eric Greisen to inform him of the problem, but have not
yet had a response.

The basic message at the moment though is you can't use ATLOD with
versions of AIPS which have changed to the right-handed terrestrial
reference frame.
