Michael,

There has been an extended non-public discussion about how
project codes are getting lost or distorted on the way to
the archive record.  Fast switching is the easiest way
to trigger this.  I am sure your data is in the archive but
the project code is not what you expect.  Also, if you do
find the data be warned that the calibrator will not be marked
with a non-blank cal code.
