Stefan, A quick answer. Is there a smarter way? Not inside ARTS itself. And, for the way I outlined, what is the currently recommended way to get out tangent altitude and opacity along the los? Note that you don't need to make a Tb calculation, you can calculate the transmission

Dear Stefan, If you have a controlfile to compute the od and tangent altitude it should be fairly easy to wrap this into a python function and use scipy.optimize.root to find the zero of od - 1.0. Cheers, Simon From:

Dear all, here is an ARTS challenge, not strictly important right now, but for my own curiosity. Probably mostly to Patrick, but perhaps interesting also for others. For exoplanet research, one observation technique provides the planet's transit radius, that is, the tangent radius where the
