Stacks on MaDCoWS cluster positions in bins of richness on the ACT maps. The color bar scale is in units of . Due to the order of magnitude difference in scale maximum between bins, the scaling is not consistent between plots. While there is no detection in the 10 < λ₁₅ ≤ 20 bin, there is a clear signal in all the other bins. The red circle indicates the central 2.4′ in diameter. The x axis shows the offset in RA in arcminutes, while the y axis shows the offset in declination in arcminutes. The text in the top left is the number of MaDCoWS cluster candidates in the stack and the S/N.
