[vsnet-chat 1333] More on all-sky photometry file

[bas@lowell.Lowell.Edu (Brian Skiff)]

     Further to my recent note about a collection of faint stars with (mostly)
published BVRI photometry, Michael Richmond (mwrsps@rit.edu) has provided
some useful 'products' based on the list.  All-sky plots of the distribution of
the stars in both equal-area and rectangular projections can be found at:

These show that there are only a few large areas outside the Milky Way that
lack some sort of photometric reference stars.  Thus most wide-field sky
patrols for variable stars, novae, asteroids, etc. will have some calibration
stars on nearly every image.  As soon as we get some persistently-cloudy
weather in Flgstaff, I will have time to add in a large number of sequences for
the southern sky, and also fill in sequences along the Milky Way.
     In addition, Michael has produced a version of the list suitable for many
types of automated analysis.  This file includes reformatted names, RA/Dec
converted to decimal degrees, and gives the BVRI magnitudes explcitly rather
than as V magnitudes and colors.  This modified file is available at:

My thanks to Michael for generating this useful version of the file.
