Fig. 6


Empirical RV precision (δvrms) for individual spectral orders of CARMENES observed in the sample stars. Each panel shows for each order the median value for all observations taken of stars with spectral types M0 and M0.5 (upper left panel), M1 and M1.5 (upper right panel), and so forth. Error bars mark the 25th and 75th percentile of all observations. Gray points show quadratically added δvrms for 100 or 200 nm wide spectral windows, as indicated by the horizontal bars. Blue and red symbols show the CARMENES VIS and NIR spectral ranges. The number of observations per spectral type is given in the upper right corner of each panel.
