Hi,

what do you intend to do with abs_coeff_user?
Do you really process this further within ARTS itself? only then it makes
sense to process propmat_clearsky_field into a Tensor3*, i think.
Else, I strongly recommend to do any re-shaping / reduction outside of
ARTS; other programming languages are much better suited for this kind of
task (e.g. you can use the matlab-interface atmlab to have easy access to
ARTS output. or the python interface typhon).

abs_coef was a Matrix of dimension [f_grid, abs_p] (and
abs_coef_per_species an Array holding one abs_coef matrix per defined
abs_species).
propmat_clearsky_field is a Tensor7 of dimension [species, f_grid,
stokes_dim, stokes_dim, p_grid, lat_grid, lon_grid].

That is, for reducing propmat_clearsky_field to what was
abs_coef_per_species before would be
propmat_clearsky_field[:, :, 0, 0, :, lat_index, lon_index] (in case of
0-indexed varibales; in case of a 1D calculation furthermore
lat_index=lon_index=0). As far as I know, that's not possible (at least not
easily possible) within ARTS itself.

Note that for deriving abs_coef for this, you need to sum up over all
species (i.e. over the 0th dimension of propmat_clearsky_field.

Best wishes,
Jana


ps.
*by the way, what are the 3 dimensions? neither abs_coeff nor
abs_coef_per_species is (or has been for a long time) a Tensor3. That is,
you must have post-processed abs_coef(_per_species) anyways?
