Notes.
The 6–5 transition is saddled by c-C3H2 transitions with rest frequencies of 251.5087, 251.5273, and 251.3143 GHz. The apparent line widths therefore appear larger toward the east and west locations, and these parameters are likely unreliable. Toward the north location, the 6–5 line width is consistent within the uncertainties of the 4–3 and 7–7 transitions.
