Hi All,
I am curious if anyone here could answer my question.
I have had a look at commander_dx12_v3_2_29.clik/clik/lkl_0/_external/sigma.fits which I believe it contains the likelihood for lowl (2 < ell < 29). It contains an array of shape
3 x 249 x 1000
I believe the first axis is for TT, EE and BB and the second axis is for ells from 2  250. I believe the third axis is the tabulated g_ell(C_ell^theory) from
Equation 12 in Planck 2018 05  CMB and likelihoods paper
https://doi.org/10.1051/00046361/201936386
The data only contains the tabulated values of log likelihood for C_ell^theory by the the values of C_ell^theory itself. I am wondering if I could somehow find the value of C_ell^theory to match the values of the log likelihood in the file.
Best,
Teera

The data only contains the tabulated values of log likelihood for C_ell^theory but not the the values of C_ell^theory itself.The data only contains the tabulated values of log likelihood for C_ell^theory by the the values of C_ell^theory itself.
Sorry for not proof read before.

Hello,
I would like to followup on the first part of this question and confirm if this is indeed the correct description for the dimensions of this 3 x 249 x 1000 array? I have also been looking at this sigma.fits file and am unsure what each axis of this array corresponds to.
Thank you for your help,
Jordan
