Comparison between PwS and AMI mean Y_tot and θ_s values. The size of the points plotted increases with increasing Planck S/N; clear detections are plotted as filled circles, and moderate detections as empty circles. Error bars are omitted for clarity and since the errors in Y_tot and θ_s are correlated. The one-to-one relationship is plotted as a black dashed line. The fitted linear relationship for all clusters (clear AMI detections only) with S/N greater than 7 is plotted as a black solid (black dotted) line.
