Fixed aperture photometry. This figure is to be compared to Fig. 7 of Planck Collaboration XXIII (2016). The y-axis shows the average flux density of a cluster, so it needs to be multiplied by 1091 (the number of clusters in the analysis) to give the total flux density of the stack. Our data points are shown as black diamonds, and the points from Planck Collaboration XXIII (2016) as red filled circles (shifted by +10 GHz for clarity). Our models are shown in blue and orange, and the model from Planck Collaboration XXIII (2016) is shown in red. The black dashed line gives the contribution from the SZ signal alone.
