Estimation of the accuracy of the radial velocities determined by the doe code on GIRAFFE setups HR10 and HR21 (Ca ii triplet region). In each case, 251 simulated CCFs with a S/N as labelled and the blue line representing a noise-free CCF (left panels) were analysed with doe varying the value of SIGMA for the calculation of the smoothed successive derivatives and of the radial velocity (right panels).

This figure is made of several images, please see below:
