Fig. 2.
RVs of Polaris at the reference epoch (c) chosen for its densest phase coverage over a short timescale. Top panel: Hermes data as a function of Barycentric Julian Date with the overplotted model consisting of the reference Fourier series model and a slow linear term of 9 ± 1 m s−1 d−1. Bottom panel: residuals of the fit, with an RMS of 13 m s−1. The grayscale traces observing date as is done for the template fits below.
