18 May 2020:
The quoted semi-major axis is for projected separation from the planet to the primary star.
But from Bennett et al. (2020) and Terry et al. (2026): "For this lens system to have stable orbits, the three-dimensional separation of either the primary and secondary stars orthe planet and primary star must be much larger than that these projected separations.Since we do not know which is the case, the system could include either a circumbinary (a_{(AB)b >>2 AUs) or a circumstellar planet."}

The parent star is a binary. The mass quoted here is the sum of the masses of the two stars: M_L1 = 0.35 M_Sun and M_L2 = 0.12 ± 0.015 M_Sun.
. The projected separation of the two stars is 2.03 ± 0.25 AU. (Bennett et al. 2020, Terry et al. 2026).
