Impact of Yx calibration¶

SPT2500d+Yx, full analysis¶

In the following figure, I show two different analyses of the sample.

• I am using a new set of SZ priors centered on 5.38, 1.34, 0.49 (Asz, Bsz, Csz).
• GREEN contours: No Yx data (but you can still see the Yx prior).
• BLUE contours: Use 78 Yx measurements.
• Ax want to stay at its low value, and pushes Asz to high values.
• This looks very similar to what Tijmen is reporting https://spt.uchicago.edu/trac/wiki/ClusterCosmology2500d_3.

SPT2500d+Yx, mass calibration only¶

In this analysis, I turn off the cluster abundance experiment, in order to isolate the impact of the Yx calibration.

• Asz is still very high.
• Ax now is closer to its prior (prior: 6.73 +/- 1.1)
• Omega_m looks very wrong. Remember that this constraint comes from the angular diameter distance involved in the Yx profile fitting, and the redshift dependence of the scaling relations.
