	(mas)	(mas)

7₁–6₁-A, ν_t = 0	−12	+0		36°
12_-1–12₀-A, ν_t = 0	−19	+0		32°

Notes.

^(a)

Averaged over [−2, +2] km s^-1 from the peak.

^(b)

The resulting error on the centroid position is a function of the channel signal-to-noise ratio and atmospheric seeing, and is typically much smaller than the beam size.

^(c)

Offsets are with respect to the peak of the continuum emission. Uncertainties are ~4 mas.

^(d)

Uncertainties are ~30 mas.

^(e)

Uncertainties are ~10°–18°.
