Visibilities for the m = 0 modes for the G2 star as a function of l and spectral line, for the 0 G case and an inclination angle of 0°. In addition to the regular lines, profiles were synthesized with larger and smaller abundances of Fe for the 6173 Å line (using the same simulations). For clarity the visibilities have, for each spectral line, been divided by the visibility of l = 0. The visibilities of the other m values are zero at i = 0°.
