Some questions about input

Hello, I am glad that PFC-TT has some amazing optimizations. I have some puzzles to ask.
What is the role of mode in input.cvs.
I understand that S. area parent bin (m^2), surface area (m^2) and f (ion flux scaling factor) exist to correct the actual flux, but I wonder what these parameters should be set according to. I can’t get relevant information from the SOLPS data.
Auto_binning is an important code connecting SOLPS and PFC-TT, but bin_index is generated in the file Binned_Flux_Data.dat mapped_fw_bins_coords.dat new_bins_coords.dat respectively, causing trouble for the correspondence of R, Z and flux data

Hi @yafeng-lab I think since this is less of a FESTIM question and more a PFC-TT / HISP question that @AdriaLlealS would be able to answer here
