[vsnet-chat 2670] Photometry file update

[Brian Skiff <bas@lowell.edu>]

     I've made some fairly substantial additions to my large BVRI photometric
reference file.  Chief among these are extracts of sequences around twenty
symbiotic variables by Henden & Munari from a paper that is "in press".
Arne Henden, nice guy that he his, made his complete photometry files available
to me for this.  In addition, John Greaves pointed me to the Mermilliod
photometry bibliography file on the Web, and this yielded another twenty new
sequences in the older literature that I had previously overlooked.  Some
additional material from recent journals has been added as well.
     The star-count is about 31,000; median V is near 13.8, with most stars
between mag. 11 and 18.  Some brighter standards are included, and for quite
a number of fields there are stars as faint mag. 22.  The collection is
intended for use in calibrating scans of photographic surveys, current wide-
field digital surveys, providing "instant" calibration for variables, GRBs,
asteroids, supernovae, etc.
     The complete files are at:

http://ftp.lowell.edu/pub/bas/starcats/loneos.phot        (2.2Mb uncompressed)
http://ftp.lowell.edu/pub/bas/starcats/loneos.phot.gz     (591Kb compressed)

...for flat ASCII and gzip-compressed versions.  The bibliographic reference
file has also been amended accordingly:

http://ftp.lowell.edu/pub/bas/starcats/loneos.ref         (113Kb)

A date given at the top of each file shows when it was last modified.  Some
sample lines are appended below.
