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), 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.
