| cos(ωt)d [ppt] | −16.3 ± 0.3 | −16.3 ± 0.3 |
| cos(2ωt)d [ppt] | −37.2 ± 0.2 | −37.2 ± 0.2 |
| sin(ωt)d [ppt] | −2.49 ± 0.08 | −2.49 ± 0.08 |
Notes. The fits were made in the same way as indicated in the caption to Table 4. (a) The prior on AV was set to cover the limited range of 0.07–0.09. (b) This result is essentially just the prior on K1. (c) This is the prediction of the K velocity of the secondary based on the fitted system parameters. (d) These represent the primary illumination term, the primary ellipsoidal light variation term, and the Doppler boosting term, respectively. Because this latter measured value is higher by an order of magnitude than is physically plausible and has the opposite sign, this is attributed to star spots on the relatively cool companion star.
