The weighting and tiling process for a simulated signal reconstructed by cWB. The skymap is shown in the left panel with the highest likelihood regions in red, and lower ranked pixels in blue, along with galaxy locations marked as black circles. The right panel shows the location and approximate size of the three chosen QUEST tiles, along with the locations of pixels that are retained after weighting by the galaxy catalog. The injection location is caught by the southernmost tile, and is marked with an asterisk.
