Notes. Titan high resolution data taken in nadir mode near the south and north pole in focal planes 3 and 4 of the CIRS instrument and analyzed here. Ls is the solar longitude at the time of the observation. The datasets marked with (*) were already included in our 2016 publication but were re-analyzed here with improved calibration.
