Hi, can you help me with a parametrized model? I this model I am trying, I have one parameter, say "alpha". I don't have w0_fld or wa_fld in the equation...

How should I proceed if I want to implement a different dark energy model? Please help!

Thank you so much! I totally missed including data.cosmo_arguments['fluid_equation_of_state'] = 'CLP'

Thank you, this helped. I used the provided best-fit values and the covmat/base2018TTonly_lensing.covmat with superupdate. The acceptance rate is now around 0.25 and the plots look nicer too with more...

Oh okay, I am actually going to use combinations now. This was very helpful. Regards, Kshitiz

Right, I got perfect Gaussian posteriors with a decent a.r. of 0.26. Thank you! Now I am going to try to modify CLASS to analyze the Planck18 data with a...

The problem is when I am using the covmat computed using --want -covmat in the sampler run, it always gives this error: Traceback (most recent call last): File "/home/kshitiz/montepython_public/montepython/MontePython.py", line...

Oh, Thank You, Sir. I ran 10000 chains a few times, and kept using and updating the bestfit values obtained everytime in the new runs. Finally when the accepted ratio...

I am worried specifically about this line: =>thermodynamics_helium_from_bbn(L:545) :could not open fA with name /home/kshitiz/class/external/bbn/sBBN_2017.dat and mode "r" pls suggest how to deal with it

Grateful for your quick reply. I had created a default.conf file with these lines in them: path['cosmo'] = '/home/kshitiz/class_public-3.2.3' path['clik'] = '/home/kshitiz/montepython_public/code/plc_3.0/plc-3.01' And as you said, in the example.param file,...
