Normalized IRAC [3.6] (blue) and [4.5] (red) photometry for the sixteen Y dwarfs in our sample. The epoch 1 data is found in the left panel and the epoch 2 data is found in the right panel. For display purposes only, outliers have been removed as described in Section 3.2.1. Note that the scale of the ordinate is different for [3.6] and [4.5] light curves. The normalized IRAC photometry is available as the Data behind the Figure in the online Journal.
