Full additional reduction steps and transmission spectra computation from STARSHIPS for telluric lines below 70% transmission masked up to 90% transmission in their wings and four PCs removed for the echelle spectral order 86 with the NIRPS-DRS data products. Top: single exposure of the uncorrected and telluric corrected flux along with the reconstructed telluric transmission spectrum, with offsets for visibility. B) Uncorrected flux, normalised by the instrumental blaze function. C) Telluric-corrected flux (correction from the NIRPS-DRS - Allart et al. 2022). D) Spectra normalised by their median (over wavelengths) and shifted to the pseudo-SRF, with a first sigma-clipping of pixels showing abnormally high variations in time. E) Spectra normalised to the continuum of the master-out. F) Spectra divided out by the normalised master-out (transmission spectra). G) Transmission spectra after final PCA-based correction, additional telluric masking, mean subtraction and a second sigma-clipping in the time dimension.
