2 x 2 grid of detection significance maps, with the colorbar indicating the SNR (signal to noise ratio) as a function of the two velocity parameters (Kp and Vsys). The four cases consider different photon SNRs (top row: high SNR, bottom row: low SNR) and different treatments (e.g., top left: radiative transfer-based tellurics, top right: data-driven tellurics).
A corner plot showing that the posteriors from the baseline simulation (teal) change under the assumption of very strongly time-varying tellurics (maroon).
A schematic of our simulation pipeline, beginning with a planet spectrum (top left), which is doppler shifted, then the star is included, then tellurics, then the blaze function, and finally processing with PCA and detrending.
Thumbs up in front of a poster.
