Searching for TTVs in the transits of TOI-672b. Mid-transit times from fits to each individual transit (described in Section 5.5) are compared to the linear ephemeris from the joint fit model (i.e. the dark grey line at y = 0 in this plot, where the 1, 2 and 3 standard deviations from the value are shaded). The TESS transits are shown as orange circles; the LCO CTIO transit is the yellow triangle; the PEST transit is the green pentagon; the LCO SSO transit is the blue upside down triangle; the ExTrA transits are purple squares; and the Deep Sky Chile CDK17 transit is the orchid coloured diamond.
