HD 34411 RVs measured with EXPRES. We zoom in on all but eight of the exposures, which were taken over 150 days later. All RVs are shown in blue; nightly binned RVs are overplotted as orange squares. The rms of the data set and the rms of the binned values are given in the top-left corner. Left: RVs derived using a polynomial-based wavelength solution. Right: RVs derived using wavelengths from the implementation of excalibur presented in this paper.
