| Data Set Abstract |
This is a compilation of mean U-B and B-V color indices of
asteroids. This data file was provided by E.F. Tedesco, MRC and
is a *preliminary* version. The version actually published will
include UBV observations published through 1994 and the
individual, referenced and commented, observations from which the
average value was obtained. This dataset presents Johnson system
U-B and B-V colors (or colors transformable to them) for
asteroids, obtained between 1951 and 1989 and published through
mid-1990. In addition, it uses Ted Bowell's unpublished
observations from the Lowell UBV Asteroid Survey. The 978 mean
U-B color indices are derived from 3,476 U-B observations. The
1,020 mean B-V color indices are derived from 4,010 B-V
observations. |
