Notes.

^(a)

Parameters for individual components are derived from Gaussian fits to the global spectra and total line fluxes are derived from direct integration of the line profile.

^(b)

The uncertainties in the VLA fluxes include an estimated 3% calibration error added in quadrature to the noise error. The calibration error in the SMA data is estimated to be 15%.

^(c)

Apparent optical depth τ_app = −ln(1 + S_line/S_cont). A covering factor of 100% is assumed and τ_app is thus a lower limit to the true optical depth.

^(d)

1σ upper limit.

^(e)

Relative to the 6035 MHz line which is located ~ 215 km s^-1 below the 6031 MHz line.
