SZ cluster counts likelihood: natural vs base 10 log in szcounts.f90

[borisbolliet]

Hi,

I think the prior on the scatter parameter sigmaM, in line:

https://github.com/cmbant/CosmoMC/blob/d34a8d34a3f61f58d8dd601519ed459b006323a0/source/szcounts.f90#L2014

should be

(cosmopar%sigmaM-0.173)**2./(2.*0.023**2.)

rather than

(cosmopar%sigmaM-0.075)**2./(2.*0.01**2.)

because I think that the routine uses the parameter sigmaM defined in natural log, as described in the 2015 Planck SZ cluster paper (table 1 of https://arxiv.org/pdf/1502.01597.pdf and footnote c of the table), as can be seen here:

https://github.com/cmbant/CosmoMC/blob/d34a8d34a3f61f58d8dd601519ed459b006323a0/source/szcounts.f90#L1282

(Or maybe I am missing a conversion from natural log to base 10 log...?)

If this needs to be corrected, then these lines:

https://github.com/cmbant/CosmoMC/blob/d34a8d34a3f61f58d8dd601519ed459b006323a0/batch2/SZ_plus_CMB.ini#L14

https://github.com/cmbant/CosmoMC/blob/d34a8d34a3f61f58d8dd601519ed459b006323a0/batch2/SZ_plus_priors.ini#L15

in the input files should also be updated to be with respect to the natural log value of 0.173\pm0.023.

Is there a way I can see the original question posed?

thanks
