Unoriented Stacks Updates

Back when I had first made unoriented stacks on clusters in the ACT y map and on the Websky y map, the two profiles had been quite different. I fixed a few things:

1) The smoothing scale was slightly different between the two (I had a factor off in the FWHM to sigma conversion of the Gaussian beam) 2) The mass bins did not match well. I was matching by number and taking the top most massive Peak Patch halos to match the number of Redmapper clusters. I think this was including more massive PkP halos. Now I am binning clusters in richness and matching the bins for halos in the sims by using the richness-to-halo mass relation from weak lensing done for Redmapper by McClintock et al. 2018. 3) The Websky map was not filtered to match the ACT y map. I now have filtered modes of ell < 80 like Mat had done to the ACT y map.

Low redshift bin

Low redshift bin stack on Redmapper clusters in ACT+Planck y map, richness > 20

Halo masses (calculated from weak lensing relation) for low redshift bin , lambda>20 clusters

Halo masses for Peak Patch halos in the same mass range + redshift bin

Radial profile comparison of stack on clusters in Websky map vs ACT map, with 2' Gaussian scaled to the amplitude of the stack on data.

Medium redshift bin

High redshift bin
