Just wondering if we will need to put a placeholder for sth. like azimuth_solid_earth_tides_applied

It is not a bad idea. Just in case it will be more difficult to change the product

What is going to happen for static troposphere correction if cfg.lut_params.enabled is True, and we apply weather-model based troposphere correction? I think this field has to be False in that case?

My hope is that when we include the individual enabling/disabling of the LUTs, each of these flags will be replaced by its own individual flag. So later on, we should have the ability to set to False (or True) each of these corrections
