Nightly Stack Dither

The stacked fits images are available from the standard MD datastore, with data_group values of MD04.20100117.ditherA, MD04.20100117.ditherB, MD04.20100116.ditherA, and MD04.20100116.ditherB.

Eight exposures of MD04 in i, from 2010-01-17. There is a shift of the center between the two dither patterns. The masked location of a crosstalk artifact is indicated with a red line connecting it to the source star.

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 (update: This looks to be a very low intensity crosstalk that was not part of the currently defined rules.). This artifact appears in the B dither, but the masked hole is filled.
