As I had to learn the hard way in the larger model tum-ens/urbs#140, accessing single values using pandas .loc[...] in a loop is wasteful. Instead convert each parameter to a dictionary with fast access. It won't be noticeable here, but with millions of accesses, accessing DataFrames for single parameter values should be avoided.
