6338.14, and 8104.87 A. In order to remove the effect of magnitude variation
due to an asteroid's rotation that could affect the asteroid's color, we always
take a pair of R -band images before and after we use other filters. Hence we
define one observation sequence as RR - BB - RR - II - RR - VV - RR .Eachof
the R magnitudes is interpolated (or extrapolated) to the value at the same
UT when we use other filters for comparison.
Since the exposure time for each image is 2-3 min, each of these
sequences takes about 40 min. While taking R -band images consecutively
