Signal-to-noise ratio (S/N) map for MS0735 for the data (left) and residual of the data minus the TOD with shock r₃ = r₁ variation (right), which is the ninth variation listed in Table 3. The contours are at steps of S/N = 1. The cross indicates the cluster center, and the circles show the X-ray-identified bubble locations. The white circle in the bottom left shows the MUSTANG-2 beam. The noise at the center of the maps is ∼10 μK.
