MaDCoWS to ACT suppression ratio due to miscentering based on the 96 co-detections. The position of data points on the x axis shows the center of the richness bin. The y axis is the ratio of the aperture δT_CMB in the central 1.2′ radius of the MaDCoWS centered stacks to that of the ACT centered stacks, where δT_CMB is the fluctuation in CMB temperature from the mean. The data have been fit to a one-parameter sigmoid model of the form . The dashed red line shows this fit, and the legend reports b.
