Map of the logarithm of 2MASS J-band star counts around the LMC with the LIGO localization contours shown in white. The DECam i-band images are shown as orange camera outlines; some of the z-band images are offset from these. The white points are the luminous red supergiant catalog developed in this Letter, with those marked red not having a visual inspection. Eight are outside our imaging area. The four remaining fell into chip gaps and/or on bad CCDs.
