Notes. (†) Blended with nearbytransitions of same species (blending taken into account in synthetic spectrum). (*) Transition shown in Fig. 7. (?)Faint emission seen at frequency of transition but blended with other unidentified transitions possible. (a) Blended with HCO+ 4–3 transition. (b) Blended with set of stronger CH3 OCH3 transitions at 356.575–356.587 GHz. (c) Blended with stronger CH3 OCH3 transition at 356.7130 GHz. (d)Blended with set of stronger CH3 OCH3 transitions at 356.723–356.724 GHz. (e)Blended with stronger NH2CHO transition at 345.1813 GHz. (f)Blended with H13 CN J = 4–3 transition. (g)Synthetic spectrum cannot account for full observed line flux. Blending with unassigned line possible (see text). (h) Blended with HCN J = 4–3 transition.
