[vsnet-chat 2176] SN1999cp field photometry

[aah@nofs.navy.mil]

As luck would have it, I did have one photometric
run during my July observing run.  I've updated
the sn1999cp.dat file using that photometric night.
The basic results are about the same as for the
non-photometric night that I calibrated using the
Tycho star.  I estimate zero point errors are in
the 0.02mag range, so this field photometry file
should suffice for visual observers.  Note: as
opposed to the original sn1999cp.dat file, you do
not have to adjust the magnitudes/colors by any
zero points.
