[vsnet-chat 1703] Re: PR Her

     The Digitized Sky Survey in the north shows the POSS-I red plates.
As far as I know scans of the POSS-II are not publicly available.  The
"second-generation" scans one can get through the STScI server (but not
Goddard's SkyView) are merely the POSS-I plates scanned at 15-micron pitch
instead of 25 microns.  As a rough guess, based on the usual limits of the
POSS-I plates, PR Per has R ~19.5 at the time of the POSS-I exposure, and
thus presumably somewhat fainter in B.  It is almost certainly more readily
visible on the POSS-II film copies, but given that it really isn't "lost"
I haven't looked for it on them.
