Available model parameters

In the following, the list of all parameters that are recognized by BASTA is listed, which is extracted from the constants.parameters() class.

Please note that these might not be available/present in the grid, and there might also be parameters available in the grid that are not listed here. If these are added to the list in the module, these can also be fitted using BASTA.
