Notes. Baseline brightness is 18.771 mag in I band and 19.822 mag in V band (Szymański et al. 2011). In each case K2 peak time and impact parameters are t0, K2 = 7512.642 and u0, K2 = ±0.084. Corresponding parameters for Zang et al. (2018) models are: (7512.724, 0.126), (7512.724, −0.128), (7512.724, −0.132), and (7512.745, 0.132) in the order as in the table above.
The two signs indicate u0 signs as seen for Earth and K2, respectively. See also Fig. 2 of Gould (1994a).
