Components of the Cerro Paranal sky model for wavelengths between 0.3 and 6 μm in logarithmic radiance units. The example with the Moon above the horizon shows the scattered moonlight, scattered starlight, zodiacal light, thermal emission by telescope and instrument, molecular emission of the lower atmosphere, airglow emission lines of the upper atmosphere, and airglow/residual continuum. The (optical) model components are described in Noll et al. (2012) except for the improved scattered moonlight model, which is discussed in Jones et al. (2013).
