Notes.

^(a)

LSR velocity of the peak emission in each spectrum. The uncertainty is the channel width.

^(b)

Minimum LSR velocity of the detected emission.

^(c)

Maximum LSR velocity of the detected emission.

^(d)

Flux density of the peak emission, with 2σ uncertainty.

^(e)

Velocity-integrated flux density of the spectrum, with 2σ uncertainty.

^(f)

There is detected emission very close to the redshifted edge of the bandpass, so we probably missed some components beyond that edge.
