Top: the final RV reduction of ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩ (blue) for HD 26965 combining the velocity measurements from 87 SSOF order models resulting in a 46% smaller SMP and 14% lower RV rms when compared to the NEID DRP’s CCF-based RVs (﹩{v}_{\star }^{{\rm{NEID}}}﹩; green) and a similar SMP and RV rms when compared to SERVAL’s template-matching RVs (﹩{v}_{\star }^{{\rm{SERV\; AL}}}﹩, orange). Another SSOF RV reduction, ﹩{v}_{\star }^{{\mathtt{SSOF}}(5,5)}﹩ (purple), is shown that was constructed using a SSOF(5,5) model for every order, regardless of AIC. ﹩{v}_{\star }^{{\mathtt{SSOF}}(5,5)}﹩ had a rms of 2.1 m s⁻¹, even lower than ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩. All RV time series are shown with their corresponding 1σ error bars. Bottom left: the residual time series for ﹩{v}_{\star }^{{\rm{SERV\; AL}}}﹩ (orange), ﹩{v}_{\star }^{{\rm{NEID}}}﹩ (green), and several other versions of ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩. The residuals between ﹩{v}_{\star }^{{\rm{NEID}}}﹩ and ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩ are similar to a time-shifted version of the measured Ca II H&K variations (see Figure 13). Interestingly, ﹩{v}_{\star }^{{\mathtt{SSOF}}(5,5)}-{v}_{\star }^{{\mathtt{SSOF}}}﹩ (purple) is also strikingly similar to the measured Ca II H&K variations (see Figure 13). The ﹩{v}_{\star }^{{\mathtt{SSOF}}({K}_{\oplus },0)}﹩ reduction (brown) was constructed using the AIC-minimum SSOF model without stellar variability for every order. Only a few SSOF models used in ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩ used stellar variability so ﹩{v}_{\star }^{{\mathtt{SSOF}}({K}_{\oplus },0)}﹩ is practically indistinguishable to ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩. The ﹩{v}_{\star }^{{\mathtt{SSOF}}(0,0)}﹩ reduction (light turquoise) was constructed using the AIC-minimum SSOF model without any variability for every order. Somewhat surprisingly given the amount of telluric variability measured by SSOF, this only adds 20 cm s⁻¹of variability, but this is because many more orders are rejected (only 68 orders are kept). Bottom right: the residual time series for the highlighted SSOF order models. The residual velocities from the KO (pink) are consistent with white noise. The residual velocities from the H₂O and O₂ separating (dark orange), Ca II H&K (seafoam green), Mg triplet and MgH band (light green), and H-alpha (light blue) orders are largely consistent with white noise, excluding an interesting shared deviation between JD 2459520-2459580.
