TESS photometric light curve of HD 49198 (top panel), phase-folded with respect to the rotation period, utilising data from all currently available sectors (s20, s60, and s73). Longitudinal magnetic field values (bottom panel) for HD 49198 with their respective error bars, phase-folded with respect to the rotation period and overplotted with a simple dipolar fit. The values for the rotation period (P_rot) and initial heliocentric Julian date (HJD₀) are provided for reference.
