Gao, Peter; Fan, Siteng; Li, Cheng +3 more

Cassini/Ultraviolet Imaging Spectrograph (UVIS) Far-UV observations of stellar occultations at Titan are well suited for probing its atmospheric composition and structure. However, due to instrument pointing motion, only 5 out of tens of observations have been analyzed. We present an innovative retrieval method that corrects for the effect of poin…
