Hi, can I possibly know the meaning of 1 in the following snippet? "V_Zn 3 1" Please see the snapshot. Also, for example, in "0 1.41538 1", I understand the first and second entries are q and defect formation energy at zero fermi level, or VBM, but can I know interpretation of third entries that is "1"?

Just something to keep in mind for development.

I think it would be good to allow specification of an indirect band gap, as currently only a single (assumed direct) band gap can be provided. I think it should only require a minor update to the code, by using the indirect gap value for the cooled carrier energies. This would extend the functionality of aTLC to indirect gap materials, which would be useful both when assuming step-like absorption (i.e. SQ limit efficiencies) and finite absorption with aTLC.

Also just to note on this point, I think it would be important to be clear in the docstrings/tutorials how the input absorption and band gap values are used (i.e. if the onset of absorption differs from E_gap, is it shifted to match or not? How else is E_gap used etc).
