MD04, g band, 2010-01-16. Dither A is comprised of 4x 240s, and Dither B is 8x 120s. The masked location of a crosstalk artifact is indicated with a red line connecting it to the source star. An unmasked crosstalk artifact is also connected with a red line to the source star. It is not clear why this was not masked. This artifact appears in the B dither, but the masked hole is filled.
