Issue on page /tutorials/tess.html and/or in documentation of get_ror_from_approx_transit_depth

This case study has: "r_pl = pm.Deterministic("r_pl", ror * r_star)" for calculating the planetary radius. According to the documentation for get_light_curve, r_pl is in units of solar radii, not the host star radius. However, this example gets ror from get_ror_from_approx_transit_depth, for which the documentation says ror is the radius ratio and is not explicit about units. I suggest clarifying in both the case study tutorial and in the documentation about the units.
