Caption: Figure 1.

A map of the logarithm of 2MASS J-band star counts around the LMC with the LIGO localization contours shown in white. The contour labels indicate the fraction of the LIGO localization probability enclosed. The dotted contours are for the initial (2015 September) skyprobcc_cWB_complete map, while the solid contours are for the final (2016 January) LALInference_skymap. There is an island of significant probability in the northern hemisphere in the skyprobcc_cWB_complete not present in the LALInference_skymap, so the dotted contours do not show the complete 50% or 90% areas. The data are shown on an equal-area McBryde-Thomas flat-polar quartic projection, as is Figure 3.
