Is there a particular reason why this has been changed? I think here the relative import should be kept.

If you look at the output of the unit tests, you will see that this change actually leads to ModuleNotFoundError: No module named 'observables'

The two lines above are exactly the same, but S6c is missing.

_observables_p = {
'P1': {'func_num': lambda y, J, J_bar, J_h: S_experiment_num_Bs(y, J, J_bar, J_h, 3)/2., 'tex': r'P_1', 'desc': "CP-averaged \"optimized\" angular observable"},

There are several issues here:

  • The function used for the prediction of ATRe is just 1/2 times the one used for ATIm, which seems to be wrong.
  • The tex name of ATRe is A_T^\text{2}, which seems to be a different observable.

_obs.set_description(obsdict['desc'][0].capitalize() + obsdict['desc'][1:] + r" in $" + _process_tex + r"$")
_obs.tex = r"$" + obsdict['tex'] + r"(" + _process_tex + r")$"
_obs.add_taxonomy(_process_taxonomy)
return _obs

These two functions make_metadata_binned_Bs and make_metadata_differential_Bs do not seem to be used anywhere at the moment.
