Is there a typo in the Planck High TTTEEE

[vitenti]

In montepython the prior A dust TE 143 x 217 is:

Planck_highl_TTTEEE.galf_TE_A_143_217_prior_center = 0.3 Planck_highl_TTTEEE.galf_TE_A_143_217_prior_variance = 0.09

But in the Planck XI 2015 paper it says:

center = 0.6 variance = 0.18

and elsewhere (https://wiki.cosmos.esa.int/planckpla2015/index.php/CMB_spectrum_%26_Likelihood_Code) it says:

center = 0.6 variance = 0.018

In CosmoMC it uses the same values as in Planck XI 2015:

param[galfTE143217]=0.6 0 10 0.18 0.1

Does anyone knows if that's a typo or if is there some reason to have a different value in montepython?

I know I'm resuscitating an old issue, but I noticed the same thing and I am curious of the reason...

To summarize all the priors I found for this parameter: _in the current version of CosmoMC, by default it's a Gaussian prior of center 0.6 and width 0.18. _in the parameters files of the "official" Planck 2015 chains on the PLA, it is a Gaussian prior of center 0.3 and width 0.09. _in the default parameter files of the current version of MontePython, it is still a Gaussian prior of center 0.3 and width 0.09. _in the Planck XI 2015 paper (page 20 Table 10), it's a Gaussian prior of center 0.6 and width 0.18. in the official Planck wiki (https://wiki.cosmos.esa.int/planckpla2015/index.php/CMB_spectrum%26_Likelihood_Code), t's a Gaussian prior of center 0.6 and width 0.018.

I suspect some of them are typos or "old" recommendations, etc...

My problem here is that by default CosmoMC and MontyPython will give different results for what people expect to be the same likelihood+priors (unless this parameter does not correlate with nothing important...).

I got an answer to the same question here : http://cosmocoffee.info/viewtopic.php?p=8380

I think we can consider the problem solved !
