Characteristics of the probability distributions for the orbital parameters of WASP-77AB.

Parameter Symbol Median Mean Mode P84 P16 P84 − P50 P50 − P16
Semi-major axis (au) a 420 490 310 660 290 250 130
Eccentricity* e 0.60 0.60 0.95 0.88 0.34 0.28 0.26
Inclination (°) i 75 70 79 81 60 6 15
Long. of the asc. node Ω 339 313 340 346 299 7 40
Arg. of periapsis ω 226 229 211 278 197 51 30

Notes. The 16th, 50th, and 84th percentiles are denoted by P16, P50 and P84. (*) The eccentricity distribution is bimodal, with moderate eccentricity and high eccentricity solutions (e ≃ 0.5 and e ≃ 0.95).
