Description:
In the Table 1 shown are the Heliocentric Julian Days at the start and
at the end of the observation runs and the numbers of the observations
for each color. Since the observations in 1991 have been published in
Li et al. (1992IBVS.3802....1L 1992IBVS.3802....1L), only those in 1992 and 1995 are
listed in Table 2a and 2b for yellow and blue light respectively,
where the Heliocentric Julian Days and the magnitude differences(the
variable minus the comparison) are given. The normal points producing
the light curves in Fig. 2 can found in Table 3 through 5.
