The near infrared airglow continuum conundrum. Constraints for ground-based faint object spectroscopy

J. K. M. Viuho, J. P. U. Fynbo, M. I. Andersen

The airglow continuum in the near infrared is a challenge to quantify due to its faintness, and the grating scattered light from atmospheric hydroxyl (OH) emission lines. Despite i…
