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

[ernewton]

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.

Hi @ernewton — I believe that the docs and the tutorial are both correct in this case. r_pl has units of Solar radii, and when we call get_light_curve, we use:

        light_curves = (
            star.get_light_curve(orbit=orbit, r=r_pl, t=x[mask], texp=texp)
            * 1e3
        )

where all the arguments have the units consistent with the docs. Can you clarify what the issue is that you're seeing?

Note that when we call r_pl = pm.Deterministic("r_pl", ror * r_star) we're converting ror from relative units to r_pl in units of Solar radii!
