Map of the IRAS 16293-2422 region from publicly available APEX data presented by Kahle et al. 2023, where the color map is N₂H⁺ (3-2) at 279.511 GHz, and the cyan contours show the CH₃OH-A⁺ 1₁−0₀ b-type transition at 350.905 GHz (beam size for N₂H⁺ is 23.7″ and shown in the bottom left corner). Crosses designate the locations of the IRAS 16293E prestellar core, labeled E, and the IRAS 16293A and B protostars labeled A/B. Other emission regions studied by Kahle et al. 2023 are labeled by white squares. For the single-pointing observations presented here, we also show the largest (ARO 12 m beam at 73″) and smallest beam size (Yebes 40 m beam at 37″).
