Retrieved CH3CN vertical abundance profiles for each epoch. To illustrate the approximate size of the uncertainties, the NEMESIS retrieval error envelope is shown in blue for the 2016 August 19 epoch. The 2022 September 6 retrieval is shown with a dashed line to indicate additional (unquantified) uncertainty as a result of extra line broadening introduced by the rubidium maser problem identified in Section 3.
