Posterior distributions and joint correlations between all free parameters in the joint fit to the In-Orbit Commissioning transit and phase curve observations sampled with the No U-Turn Sampler. The parameters include: the mid-transit time t₀, limb-darkening parameters u₀, u₁, the ratio of planetary to stellar radius R_p∕R_⋆, the impact parameter b, the eclipse depth δ_ecl; two sets of detrending vector weights for the following vectors, one per visit: the ThermFront 2 temperature sensor reading, thecosine and sine of the roll angle, and a unit vector; the amplitude of the piecewise-Lambertian variations A; and the startand stop longitudes of the lower-reflectivity region ξ₁ and ξ₂. The last parameter, log σ is the natural logarithm of the flux uncertainty for each measurement.
