Phase-folded and detrended RV time series of TOI-732 b (top) and TOI-732 c (bottom), obtained after subtracting the signal of the other planet. The corresponding Keplerian model is superimposed in red. The different colours mark different instruments, namely HARPS (black), IRD (light green), HARPS-N (blue), CARMENES (magenta), iSHELL (cyan), MAROON-X (yellow, orange, and deep green for observations taken in February, April, and May 2021, respectively). As MAROON-X has two different channels, full and empty symbols represent data acquired using the blue and red channel, respectively (see text for further details).
