Fig. C.1


Circulation velocities vac of the average supergranule outflow region at solar latitude 40° derived from HMI and MDI Dopplergrams (after the correction for center-to-limb systematics). The velocity maps were obtained by applying the respective conversion factors from Appendix B to the travel times τac. The limits of the colorscale are arbitrarily set to ± 15 m s-1.
