The ZCRET error 1 says that the file already exists.  Somehow, you
have gotten the work file created but not in your catalog file.  I
first thought to recommend the - outside AIPS - tool RECAT but that
would work only if this dangling file also has a header file.  You
need to determine which disk area the file is in and which one of the
UVDccc001.uuu; files it is.  The ccc is the catalog number and there
should be other ??Dccc???.uuu; files as well (uuu is your user
number). 

The RECAT business is probably worth a try.

cd $AIPS_ROOT
source LOGIN.CSH   (or . LOGIN.SH)
$CDTST
cd your data area
mv CAD000000.uuu\; CAD000000.uuu.save
RUN RECAT

and answer questions.  Have it look for catalog numbers much larger
than you think should occur.  See if
W44-EF      .IMAGR .   1
is listed as being found.  You can also re-run aips and see if it
appears.  If not you will need to find the file some other way and
delete it.
