Hello,
I am running cosmomc adding a new parameter. The programme is running fine but I am getting a message
Code: Select all
Chain:0 drag accpt: 0.392441869 fast/slow 99.7411499 slow: 44373
Chain:1 drag accpt: 0.390350789 fast/slow 99.8655319 slow: 44234
Chain:3 drag accpt: 0.390274107 fast/slow 99.8365173 slow: 44224

lklbs_lkl(../src/lklbs.c:219)::ForwardError
simall_lkl(../src/simall/clik_simall.c:48)::Error 1233 (multipole EE 29 too large (got 0.307382 expected <0.3))
I will be grateful if I can get some help to remove this error.

[math]Hi Akhilesh
The Planck low ell EE likelihood caused the error.
It is complaining because the power spectrum your explorer fed it is very weird and clearly out of the range of validity of the computation. If you look at Fig.8 of Planck 2018 V. you will notice that the EE spectrum and sims upon which the likelihood is based are of the order of a few hundredth [math]\mu K^2 [D_\ell] at [math]\ell=29, while the model you are exploring is ten times larger (the values quoted in the error are in[math]D_\ell).
