Notes. The stars are listed in order of increasing TIC (TESS Input Catalogue) number (Col. 1), with another ID (preferably the HD number) given in Col. 2 and the V magnitude in Col. 3. The eliocentric Julian Date (HJD) of mid-observation, the instrument with which it was obtained (S = SALT-HRS; F = FEROS; C = CAOS; H = HARPS-N), and the resulting S/N appear in Cols. 4 to 6. The values of T_eff in Col. 7 are as listed in Paper I and Paper II. The following columns contain the results of our measurements: the stellar radial velocity v_r and its uncertainty σ(v_r) (Cols. 8 and 9); the mean magnetic field modulus ⟨B⟩, its uncertainty σ(⟨B⟩), and the number N_g of Gaussians fitted to the Fe IIλ 6149 Å line for its determination (Cols. 10 to 12); the mean quadratic magnetic field ⟨B_q⟩, its formal uncertainty σ(⟨B_q⟩), and the number N_l of diagnostic lines from which it was derived (Cols. 13 to 15); the upper limit (v sin i)_max of the projected equatorial velocity and the formal uncertainty σ(v sin i) of the v sin i determination (Cols. 16 and 17). The values of the radial velocity and of the projected equatorial velocity are derived from analysis of the same sample of N_l lines as used for the ⟨B_q⟩ determination. For spectra in which the Fe IIλ 6149 Å line is not resolved into its magnetically split components, the entries in Cols. 8 to 10 are left blank; ‘0’ in Col. 11 identifies those spectra in which the mean quadratic magnetic field is below the detection threshold, and ‘0.00’ in Col. 14, those spectra in which the rotational Doppler broadening is below the detection threshold.
