Improving the Detectability of Faint Emissions with MAVEN IUVS Echelle: Applications to Deuterium Lyman- and the D/H Ratio

Résumé

The Mars Atmosphere and Volatile Evolution (MAVEN) mission's Imaging Ultraviolet Spectrograph (IUVS) high resolution echelle channel can resolve observations of hydrogen and deuterium Lyman-ɑ as well as O triplet FUV emissions. D Lyman-ɑ is too faint to be measured above the detector noise level when Mars is far from perihelion. Lessons learned from 5 years of IUVS echelle observations have been applied to produce a new data reduction pipeline in which the faint D emission can be better resolved.
