Notes.

^(a)

Value of the fitted baseline at the line center.

^(b)

Values from fits of a convolution of a sinc function and a Gaussian function to the lines, numbers in parenthesis indicate 1σ uncertainties from these fits.

^(c)

The tentative P-Cygni profile in this line has been fitted using a combination of one absorption and one emission component. During the fitting, the frequencies for these components were held fixed at the positions of maximum emission and absorption in the feature.

^(d)

Blended with CO J = 10−9, the total flux in the line is 1135.5(79.2)Jy km s^-1.

^(e)

Likely to be affected by the sinc profile of the nearby H₂O 4₂₂ → 4₁₃ line.
