check the SN distribution of the values in filtered maps¶

The SN distribution on SZ-null filtered maps are perfect Gaussian.
The different colors represents different Rcore sizes filtered maps.
And the smooth curve is the Gaussian distribution.

by sptmap/checksndistnull.pro

test on false detection rate¶

Check the false detection number density at different SN and Rcore.
Further estimate the relation for random match prediction.

Mock false rate based on 100 simulations (no Ysz signal from cluster)

Mock fasle detection's Rcore distribution

We have the estimation as:
SN > 5: 0.007 [deg^-2]
Mean area: 10.6 [arcmin^2]

use sptmap/checknull.pro to estimate the random matching rate

SN-zeta relation check on high mass end clusters¶

Check the clusters with mass > 8e14 -> 6 clusters
The SN error doesn't improve much. still 0.9

• Kurtosis / skewness are small (0.01 and -0.05)
• K-S test (fit sigma): 0.026767578 0.77794019
• K-S test (1-sigma): 0.025215746 0.83560780

Check the clusters with mass > 6e14 -> 21 clusters
The SN error doesn't improve much. still 0.9

• Skewness / Krutosis : 0.013597445 0.030434153
• K-S test (fit sigma): 0.011321978 0.94951807
• K-S test (1-sigma): 0.030005940 0.044663965
  

zeta-mass relation check¶

21 clusters with M > 6e14 Msun/h
scaling relation from V10:
Asz = 4.92
Bsz = 1.43
