Table 2: Archival longitudinal magnetic field measurements. ¹ Borra & Landstreet (1980); ² Glagolevski et al. (1985); ³ Chountonov (2001). Phases are calculated according to the ephemeris described in the text.
Table 3: Final averaged LSD Stokes I and V profile sets and their corresponding inferred longitudinal magnetic fields. Profiles 1-13 correspond to MuSiCoS spectra; profiles 14-18 corresponds to ESPaDOnS spectra. Phases correspond to the time of mid-observations, and are calculated according to the ephemeris described in the text. N_V is the noise level in the Stokes V profile. Longitudinal fields are measured from both the Stokes V and diagnostic null spectra N, and are reported (along with their associated detection significance z) in the final 4 columns.
Table 4: Longitudinal magnetic field of $\alpha$ And inferred from FORS1 measurements.
Table 1: Journal of MuSiCoS (2000 and 2003) and ESPaDOnS (2005) spectropolarimetric observations of $\alpha$ And showing UT date, HJD, phase, total exposure duration and S/N. Phases are calculated according to the ephemeris described in the text.
