Comparison of the new (2022) and 2014 HST/COS spectra of Mrk 841 in the Lyα (top panel) and C IV (bottom panel) regions. No broad, blueshifted, UV absorption features appear in the new data, consistent with our no-obscuration interpretation. The gaps in the 2014 spectrum are due to the instrumental setup of that observation.
