Interestingly, it gives a lower mass sin i for proxima b, only 1.0 earths, which is used in the latest paper to estimate a proper mass of 2.1 earths.

Quote:If we assume the coplanarity of the orbits of the planets Proxima b and c, the de-projected mass of the close-in planet is mb = 2.1 +1.9 −0.6 M⊕ (adopting mb sin i = 1.0±0.1 M⊕ from Damasso et al. 2020).

Strange. Maybe I should leave this alone for a while and see where it goes.
