PHOTOELECTRIC V PHOTOMETRY OF HR 454

This file contains differential photometry of the newly discovered variable
star HR 454 in the V-band of the UBV system, using 51 Andromedae as
the comparison star. These observations were made at seven different
observatories; the observer's last name is given.

The first column is heliocentric Julian date, the second column is the
number of individual differential measures contained in each mean. The
third column is the mead differential magnitude, in the sense variable
minus comparison. The last column is the standard error of the mean.

More details are given in the paper published by Barksdale et al. (1984)
in I.B.V.S. No. 2632.
