Left and centre: radial velocities (HIRES, green dots; ESPRESSO18, blue dots; and ESPRESSO19, orange dots), model components (GP, red; and Keplerian, grey), and median circular model (black) for TOI-260. We have separated the RVs into two plots for ease of viewing, as there is a ≈2000d gap between the HIRES and ESPRESSO RVs. The error bars show the RV errors and jitter added in quadrature. The instrumental systemic velocity has been subtracted. The GP fits to the S_MW and FWHM activity indicators are also shown (dotted green lines) for comparison. Right: phase-folded radial velocities plus median Keplerian, following the same colour scheme.
