hi,

I've run into a problem with the 31DEC06 version of VBGLU when running on JIVE
data. We have a binary installation and the last MNJ was 2 days ago. For 2
different experiments I found that the 31DEC05 version runs fine and takes
about 1 hour, but the 31DEC06 version takes 16 hours and gives the following
messages:

      VBGLU1: Task VBGLU  (release of 31DEC06) begins

      VBGLU1:     THIS SUGGESTS THAT THESE SU TABLES WERE NOT WELL MATCHED
      VBGLU1: Run INDXR to create a new index (NX) table for the output file
      VBGLU1: Appears to have ended successfully



The input files are 2 polarizations of the same IF. The SU tables are identical
in the 2 input files. Looking at the output SU table, all the source names
have been replaced with the name of the first source. Below are the first lines
of one of the SU tables before VBGLUing followed by the first lines of the SU
table after VBGLUing.
