Results of injecting models of various strengths into our data, and repeating the Doppler cross-correlation process. In all panels, the magenta line represents the original data and the black line represents the data with a model injected, where the strength of the injected model is indicated in the bottom left corner of the panel. We note that this percentage refers to a percentage relative to the normalized flux, i.e., a percentage of the stellar surface area. The dark gray contour represents a 1σ confidence level, while the lighter gray contour represents a 3σ confidence level. The relevant planet and element are indicated on the right-hand side of each row. For HAT-P-12b we phase-fold the data to the planet’s orbital radial velocity K_p = 130 km s⁻¹, and for WASP-69b we phase-fold the data to the planet’s orbital radial velocity K_p = 127 km s⁻¹. We also take into account the orbital systemic velocity of each system; see Tables 2 and 3.
