[vsnet-chat 6161] Re: Photometry reference file

     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.

Brian (or anyone else):
I downloaded the files and they came out just fine.  One question, is there a software package that can be used to search for stars from the database within a given field?  For example, in VizieR you can type in a RA/Dec position and get all the catalog references within say 10' of that position.  Is there a simple software interface that gives this feature?

Thanks,
Doug West
