Doppler shadow for HD 148193. Left: The observed Doppler shadow created by subtracting the in-transit CCFs from an average out-of-transit CCF. Middle: Model Doppler shadow. Right: Residuals from subtracting the model from the observed shadow. The summed residuals are given in the adjacent panels. The color bar demarcate the contrast. Green horizontal lines denote points of first (solid), second (dashed), third (dashed), and fourth (solid) contact. The solid, orange, vertical lines denote ±v sin i_⋆.
