Subplanetary velocities for WASP-50. Subplanetary velocities for WASP-50 with color-coding as described in Fig. 1. The dark shaded area correspond to the time the planet is completely within the stellar disk and the light shaded area denote ingress and egress. The errorbars include a jitter term, where two separate terms have been added in quadrature; one for the epochs for the full transit and one for the epochs when the planet is partially outside of the limb of the star. The horizontal black lines in the top panel mark v sin i_⋆ from the fit.
