Caption: Figure 5.
(a) and (b) In-transit radial-velocity measurements of the TOI-1268 system using the NEID spectra. The blue dots and black bars are NEID RVs and their corresponding uncertainties. Using the RM effect, the projected stellar obliquity is constrained. (c) The Doppler tomography signal of the TOI-1268 system during TOI-1268b’s transit. The left, middle, and right panels are data extracted from the NEID spectra, best-fit model, and the residual of the data after subtracting the best-fit model. The color scale presents the flux variation of the velocity channel. We expect to observe a decrease in flux in the velocity channel of the star blocked by the planet.
