Notes. (a) Integrated flux density. (*) indicates a tentative detection. (†)Indicates an uncertain measurement due to a partial overlap with the wing of an adjacent line. Aperture gives the radius of the spectral extraction aperture; Rmin and Rmax give the minimum and maximum angular extents of the emission, measured from the continuum peak for a zeroth moment map made by summing over the channels in the velocity range indicated, and θR is the angle between Rmin and Rmax. Angular extents are omitted for unresolved emission. ND indicates a non-detection.
