CAMB scalar power spectra for different omega_lambda
Posted: April 09 2019
Dear all,
I'm new to camb and new to cosmology. In one of the homework we are asked to plot l(l+1)C_l for Omega_Lambda=0.7 but with Omega_matter varying from 0.1 to 0.3. However, this seems inconsistent with camb's parameter setting. In particular, there is no direct parameter for Omega_Lambda and Omega_matter.
I tried to set ombh2=0.0, omch2=0.1, mnu=0.0, omk=0.2, which might impose Omega_Lambda=0.7 but it does not work through, I got error "camb.baseconfig.CAMBValueError: Parameter values not set".
I'm very sorry for this simple question and will very appreciate any guidance!
Thanks,
Bowen
