Description:
Table 2 reports the journal of observations. For each date the
measured magnitudes and their uncertainties in the four filters
together with the used telescope are given. In some occasions several
images were made in the course of the same night to search for
intraday variability; these nights are indicated by an asterisk. The
magnitude uncertainties have been evaluated by taking into account the
mean dispersion of the internal error, but not the errors on the
absolute calibration.
