[daip] FITLD dies trying to read eMERLIN UVFITS

Hi again Eric,
The eMerlin data I have is from comissioning observations last august.
I assume they will comply with the CQ-requirements when they ship more
final data. According to some investigations I think DIGICOR -1 is
what I want.

However, I still cannot load the data in 31DEC12 or 31DEC13. Even
after running a MNJ. I assume I am missing something here. I run the
do_daily script, it connects to NRAO, no errors reported. But I see no
update of FITLD either. I tried loading a small section on another
compute with 31DEC11 and it works fine. The 2011-version doesn't
complain about anything when reading these files. I'm confused. Do I
need to add or change something in the MNJ script to get this patch?

Best regards,
Eskil
