Abstract:
A second catalogue of uvby-beta photometry for 553 high-velocity stars
is given; nearly all of these stars come from the Lowell Proper Motion
Survey. These data have been taken and reduced using the same
photometer, same observing techniques, same standard stars and
photometric values, and same reduction programs as the "northern"
observations of the first catalogue (Paper I). The errors of these
data are very similar to those of the previous catalogue; for most
stars the mean errors of V, m1, c1 and beta are less than ± 0.008
mag., and less than ± 0.005 mag. for b-y.
