Code: Select all
PK=camb.get_matter_power_interpolator(pars,zmin=98,zmax=100,nz_step=100,nonlinear=False,var1="delta_tot")
I then tried to do the same with the CDM power spectrum, by setting changing
Code: Select all
transfer_power_var=2
Code: Select all
PK=camb.get_matter_power_interpolator(pars,zmin=98,zmax=100,nz_step=100,nonlinear=False,var1="delta_CDM")
so the power spectra are no longer the same. Am I right in expecting them to be the same, or am I attempting to get the CDM power spectrum the wrong way? Do var1 and var2 not select which fluids we want power spectra for?
