Hi Witali, The error means that your lines' quantum numbers are defined in a way the ARTS Zeeman module cannot understand (we need F or J to do these computations). If you print the line catalog, you will probably see several "0/0" in there for the lines you have defined as using Zeeman effect. Is this correct?
If it is correct, the steps to fix this is to limit where you activate the Zeeman effect, and to define the quantum numbers there correctly. In your "abs_species", however you have defined it, you should limit the Zeeman species to just the few lines you wish to compute it for. This is often done by simply adding "-FLOW-FHIGH" at the end of a species, and then have the species without the "-Z-" defined after the limited species in a different entry. As an example: abs_speciesSet(species=["O2-Z-66-50e9-55e9", "O2-66"]) Now the abs_lines_per_species variable that lbl_checkedCalc takes should have an entry with only the few lines between 50 and 55 GHz. All of these should already have their quantum numbers defined correctly in all standard ways to define them. If you still encounter this problem, you need to manually add the quantum numbers because your original catalog is not well-understood... (Note that you must ensure that you have line mixing defined in your line catalog for O2 16-16 or the above tags will anyways just produce nonsense around the lines.) If it is not correct that you see many 0/0's, please tell me what it looks like and I will try to figure out the problem.
