Notes. The date of the observations (within March 2012) is mentioned in the first column and, in the second column, the number of sequences (N) collected within a given night is given. For a given night, UT1 and HJD1 refer to the precise date of the beginning of the first sequence collected during the night, while UT2 and HJD2 refer to the precise date of the beginning of the last sequence collected during this same night. Time exposure (in seconds) does not include the CCD readout time. The last column reports the mean peak S/N of all the V sequences on a given night.
