Hi Doug,
I imported the database into The Sky to give each
catalogue star a little red cross. That worked very well. If you
want I can send you the appropriate files.
Cheers
Peter Nelson

I have put a new copy of my large
photometry reference file at the Lowell ftp area:
http://ftp.lowell.edu/pub/bas/starcats/loneos.phot
(2.8Mb) http://ftp.lowell.edu/pub/bas/starcats/loneos.phot.gz
(700Kb) http://ftp.lowell.edu/pub/bas/starcats/loneos.ref
(128Kb)
...for the flat ASCII, gzip-compressed, and reference files,
respectively. There are not a lot of new
additions, only minor changes. The file contains BVRI photometry as
available for some 33800 stars all over the sky with V > 10; most of
the stars are between 12th and 18th magnitude. It is thus suitable for
calibration of wide-field images and other tasks. Most of the stars are
in sequences near variable stars and supernovae, active galaxies, on the
periphery of star clusters, etc. Though some bona-fide standard
stars are included, in general the intention is to provide local
zero-point stars reliable at the ~0.05 mag. level or
better.
