Notes. Columns are the beginning time (Δt), length (texp) of the exposure, optical filter used for the observations, magnitudes (with errors), and reference to the telescope used for each observation. Magnitudes have not been corrected for Galactic absorption along the line of sight (E(BV) = 0.05, Schlafly & Finkbeiner 2011).
