Notes. Masses, radii, and semi-major axis a are expressed in units of the nominal solar mass and radius (
, 
) as recommended by 2015 IAU Resolution B3 (see Prša et al. 2016), and the adopted solar temperature is 5772 K (2015 IAU Resolution B2). Bolometric corrections are from the work of Flower (1996), with conservative uncertainties of 0.1 mag added in quadrature, and the bolometric magnitude adopted for the Sun appropriate for this BCV scale is 
(see Torres 2010). See text for the source of the reddening. For the apparent visual magnitude of V643 Ori out of eclipse we used V = 9.365 ± 0.020 (Sect. 3.1, with a more conservative error).
Measured projected rotational velocity (Imbert 1987).
