[daip] Difficulty with DBCON

Hey there,

I'm trying to concatenate two databases in DBCON and I'm encountering an
unexpected error. I looked through the previous DAIP logs and found two
similar cases, but neither fits mine.

The error I get is:

DBCON1: Task DBCON  (release of 31DEC11) begins
DBCON1: RA does not match, will shift second
DBCON1: IF       AXIS HAS UNEQUAL ATTRIBUTES
DBCON1: Purports to die of UNNATURAL causes
DBCON1: localhost    31DEC11 TST: Cpu=       0.0  Real=       0
AIPS 1: Resumes

The image headers for the two files are:
