Orbital phase coverage for the LOFAR observations of τ Boo b. The observations from this study and Turner et al. (2021) are shown in the top and bottom panels, respectively. The orbital phase was calculated relative to periastron of τ Boo b using the ephemeris (period = 3.312463 days, T(0)_per = 2446 957.81 JD) from Wang & Ford (2011). The τ Boo LOFAR observations with the tentative detections (L569119 and L570725) from Turner et al. (2021) are displayed in red.
