The molecfit telluric correction step. For visits c1 (upper left), c2 (upper right), and b (lower center), we plot an example uncorrected spectrum, the corrected version of that spectrum, and the transmission function used to make the correction. The wavelengths of the helium triplet are indicated in red.
