Spectral atlas of the blue arm of MAROON-X. The grey data points show the unbinned transmission spectrum for each spectral order. The black data points provide the binned spectrum (x10). Additionally, the templates with significant absorption lines are plotted to identify the absorption lines in the transmission spectrum. The templates have been broadened to fit the resolution of the spectrograph. The dark blue spectrum shows a model telluric transmission spectrum to identify heavily contaminated regions.
