Fig. 9.
Curvature estimation for one spectral line. Left: rectified input image cut out from the wavelength calibration frame. The order trace yc(x) is marked in red. Right: best-fit model image. The extracted tilt is marked in red. We only fit a linear tilt here. Data come from ESO/CRIRES+ Fabry-Pérot interferometer.
