Analysis of chromatic TM RVs. Three columns: results for the blue, green, and red regions, corresponding to the wavelengths between 440–570 nm, 570–690 nm, and 730–790 nm, respectively. Top and middle panels: ESPRESSO RVs phase-folded at the 11 and 5-day periods, together with the maximum likelihood solution for each signal. Bottom panels: posteriors for the GP amplitude, η₁ RV, with the posterior median and 68% quantiles as labels.
