Signal-to-noise map of X-ray residuals in the 0.5–2 keV band, after removing the point sources. The black circles show the location of the primary identifications. The solid red circle is the center of the Kurk superstructure and the solid green sources are other peaks on the photo-z at z = 1.6 with sufficient spectra and the blue circle is a photo-z peak with just one spectrum, all found in the map of Kurk et al. Small solid circles indicate the spectroscopic members of the 1.6 wall and the dashed red circle is the highest significance X-ray source at z = 1.6 presented in Tanaka et al. (2013). The radii of the circles correspond to R200, also giving a sense of the angular/physical scale (e.g. Tanaka’s group has a radii of 0.7′), with the coordinates of the circle centers listed in Table 4.
