Notes.Column (1) Target of campaign. (2) Date of each observation in UT. (3) The total time observed per night for each observation, in hours. (4) The exposure time for each observation in seconds, followed by the binning factor used to increase data point S/N. (5) The mean photometric error for light curve data points per night. (6) The VATT Arizona photometric waveband used (I: ~7200–9100 Å). (7) Telescope and detector used for a given observation. These observations were taken over 4 separate epochs, spanning ~62 h of data over a 2 year baseline.
