RE: A Data Reduction Proposal

[<aah@nofs.navy.mil>]

One thing to keep in mind, for a database that is going to
last some number of years, is that you need to include fields
for proper motion.  For TASS, all of the stars will be present
in the final UCAC catalog, which will include proper motion,
so we don't have to calculate p.m., but there are quite a few
stars that move perceptibly in short order.  I'm having to
revise my internal database to account for this, especially
with some of the Landolt standards like GD71.
