Thanks for mentioning this, Jim.  I think it is partly because VSP
doesn't recognize these fields, and the calibration photometry does
not appear in the compstar database right now.  We have some reloading
of new fields into the database that needs to occur, and we need to
check our records to ensure that nothing gets overlooked.  It may be
January before that can happen, so in the meantime, just use Gord's
finding charts and the compstars he has listed there.

Sampling rate was discussed in the Alert Notices 354 and 348.  Gord
will have to tell you priority!
