     I suggest you use the generic address daip at nrao.edu.  Then anyone
working with the group will get your questions and one (or more) of us
will respond.  In particular, there are others in the group who are
more knowledgeable about VLBI than I am.

If you have already read them in, use DBCON.  FITLD has a DOCONCAT
option which allows the data to be concatenated to a pre-existing file
in many cases.  Very recently in the 31DEC03 version of aips I added
the option to FITLD to read multiple disk files in one execution -
they have to be named e.g. file_1, file_2, file_3 etc and you set
infile to file_ or file_1.  You would have this only if you have run
the MNJ on 31DEC03 since October 16, 2003.
