Caption: Figure 5.

Left panel: radial velocities for TOI-1338, phase-folded on the binary orbital period of 14.61 days, taken with the CORALIE instrument (blue and orange) and HARPS (red). Right panel: residuals to the single-Keplerian radial-velocity fit over time. The change in CORALIE residuals between blue and orange measurements coincide with a fiber change (see the text for details).
