Arne Henden has pointed out that some folks have been using my large
photometric file as though the stars were high-weight standards. This is at
least partly my fault, in naming the file 'loneos.stds', even though I have
always noted in describing the file that the stars are nothing like bona-fide
standards. It is intended that the data be used for "pretty good" calibration
of wide-field images/photos or for local recalibration of stars in large
surveys. In hopes of helping this, I have added a disclaimer/warning at the
top of the file and changed its name. Yet more new fields have been added
in the past week as well. It is copied out to the Lowell ftp area at:
http://ftp.lowell.edu/pub/bas/starcats/loneos.phot (1.5Mb uncompressed)
http://ftp.lowell.edu/pub/bas/starcats/loneos.phot.gz (427Kb compressed)
A small bibliographic reference file is at:
http://ftp.lowell.edu/pub/bas/starcats/loneos.ref
The current version of the file (8 April 1999) contains 21600 stars
mostly between mag. 12 and 18, with a median value close to V=14.0.
