Notes.

^(a)

Integration time of the individual image. Stacked images are given as number of images times exposure of an individual image.

^(b)

All magnitudes in this table are in the AB system and uncorrected for Galactic foreground extinction. The quoted error is statistical only, and there is an additional systematic error in the absolute photometric calibration, which is estimated to be around 0.05 mag in JH and 0.08 mag in K_s.

^(c)

T₀ is set as the time of the Swift/BAT trigger, i.e., 2012-08-15 02:13:58 UT.
