Notes.
^a The first seven time points are obtained from the published light curves (Hartman et al. 2011) through separate fits, the others are from our photometric data. As mentioned above, the epochs (239, 241) were followed by two telescopes simultaneously.
^b For more information about the FLWO telescope, see Hartman et al. (2011).
