### Cosmomc Clik_compute:Forward Error with EE

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

clik_compute(../src/clik.c:391)::ForwardError
distribution_lkl(../src/minipmc/distribution.c:219)::ForwardError
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.

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 at , while the model you are exploring is ten times larger (the values quoted in the error are in).
