The net Doppler shifts of Kesseli et al. (2022) (error bars) as compared to this work’s models (crosses). The first phase bin is drawn thinner than the second phase bin; observed phase bins are connected by a dotted line for visibility’s sake. The species are ordered and colored by total observed detection S/N. Rows without crosses correspond to species that we could not recover via cross-correlation in our models. Our models are able to explain some species (e.g., Na), fail to explain others (e.g., Cr) and fail to detect yet others (e.g., K).
