Most of these parameters should work well generally, and should not be changed except for tests. We will discuss only some of the more important ones. You can choose whether to have only the thick and thin disk (low and high BH accretion rates, respectively), or you can also include the slim disk at super-Eddington rates with ``include_slim_disk``. You can control what type of feedback you (do not) want with ``include_jets`` and ``turn_off_radiative_feedback``. If you choose to turn off jets, everything will be modeled as a thin disk (regardless of accretion rate), since jets go hand-in-hand with the thick and the slim disk. Similarly, if you turn off radiation, everything will be treated as a thick disk.
