Caption: Figure 2.
In-transit spectra of TOI-4010 b (first panel), TOI-4010 c (second panel), and TOI-4010 d (third panel) in the stellar rest frame. Gray lines are the in-transit spectra throughout the night. The average in-transit spectrum is shown in black. Red vertical dashed lines denote the wavelengths of the three helium lines. The red shaded regions correspond to the location of a telluric OH line and are masked in our analysis.
