Multiepoch relative RVs of Kepler-444 A measured from HET/HRS (top) in this work and from Keck/HIRES after (middle) and before (bottom) the CCD upgrade on 2004 August 18 UT by Sozzetti et al. (2009), Dupuy et al. (2016), and Butler et al. (2017). We use open circles to mark two relative RV measurements excluded from our analysis (see Section 3.3). Linear fits of relative RVs are shown as dashed lines, and we label the fitted RV slopes and rms, as well as the total number of RV measurements used in our orbit analysis.
