The system change at the VLA occurred on June 27, not July 27. The
error in FILLM affects both of your observations. You can use a
corrected version of FILLM - 07 and 08 versions after March 5, 2008 to
re-load the data. Copy your CL and FG tables from the already processed
files. Then re-run PCAL and any cross-hand imaging that you did.
I am sorry for the error.
