Planck y-map stacked on RedMaPPer Cluster Catalog

In the following plots, I am using the catalog described on the website as "Y3A2 Gold 2.2.1 sof colors, redMaPPer v6.4.22+2, Full, lambda>20." There are 53,610 clusters in this catalog.

Random orientation, map FWHM 10'

This can be compared with Connor Bevington's stack on WHL clusters:

QU orientation, map FWHM 10'

I was suspicious of this stack because it didn't seem to be centered on a cluster, so I also did a stack on random points in the map and compared them side-by-side. The difference was only noticeable when doing very specific scaling (here I am using SAO DS9 and scaling by "histogram"):
