wCDM with Planck in MontePython

Post by Shahbaz Alvi » March 09 2020

Hi,

I am trying to reproduce the Planck constraints on wCDM model using MontePython. However, some hours into the run, MontePython throws this error from CLASS.

Cosmological Module Error:
/|\ Something went wrong when calling CLASS
/_o_\ Error in Class: Class did not read input parameter(s): w0_fld, wa_fld


This error is preceded by several other errors that are too large to put here. The parameter file for MontePython has the following structure.

data.experiments=['fake_planck_bluebook']

data.parameters['omega_b'] = [ 2.2237, None, None, 0.028, 0.01, 'cosmo']
data.parameters['omega_cdm'] = [0.1201, None, None, 0.0027, 1, 'cosmo']
data.parameters['100*theta_s'] = [ 1.04090, None, None, 3e-4, 1, 'cosmo']
data.parameters['ln10^{10}A_s'] = [ 3.054, None, None, 0.0029, 1, 'cosmo']
data.parameters['n_s'] = [0.9651, None, None, 0.0074, 1, 'cosmo']
data.parameters['tau_reio'] = [0.0590, 0.04, None, 0.013, 1, 'cosmo']
data.parameters['Omega_k'] = [0.0, None, None, 0.005, 1, 'cosmo']
data.parameters['w0_fld'] = [-0.900, -1.0, -0.300, 0.08, 1, 'cosmo']
data.parameters['wa_fld'] = [0.000, None, 0.000, 0.1, 1, 'cosmo']

data.cosmo_arguments['Omega_Lambda'] = 0.0

It would be helpful if someone can lend some guidance into what I am doing wrong.

Thanks for your time to read this.
