Notes. HCO+ outer radii (Col. 2) for the assumed temperature (Col. 3). Columns 4−5 are the line flux and width. Cols. 6−8 indicate the S/N for line detections. Column 9 indicates interferometric radii Rinter (or, when in italics, Rsingle from reference [17]), for the molecules and references given in Col. 10.
