If one uses the class command line binary, one can specify the power spectrum amplitude either as:
A_s = 2.215e-9
or as
sigma8 = 0.8607
and class will automatically find the right A_s to match sigma8.
With classylss this does not work: one gets
UserWarning: Class did not read input parameter(s): sigma8
and the output Sigma8/A_s are the defaults.
It would be nice if this did work!
