[daip] problem with FiTS file

[Lawrence Rudnick]

Sorry, I hadn't seen this first note.  The error comes from any routine 
that i try to run on the file once it's loaded into AIPS.  I tried SUBIM 
and MWFLT.
I'm on my way back from Munich now, so unless I get a spare moment to 
try, I'll hit you again (with more data) upon my return. thanks.
