Left: Standard deviation (STD) of the measured (solid lines) and simulated (dotted lines) relative SC (1628 spectral bins) absolute coherent fluxes |Γ_SC43|, ..., |Γ_SC21|, combined SC fluxes $\sqrt{F_{\mathrm{S}\mathrm{C}4}{F}_{\mathrm{S}\mathrm{C}3}},\dots ,\sqrt{F_{\mathrm{S}\mathrm{C}2}{F}_{\mathrm{S}\mathrm{C}1}}$, and FT (6 spectral bins) absolute coherent fluxes |Γ_FT43|, ..., |Γ_FT21| (different shades) for an example exposure at high airmass, shown for the six baselines (43, ..., 21) and their respective baseline averages ⟨·⟩_b (different colors from top to bottom). Right: Same as the left panels but for an exposure at low airmass.
