Notes.

^(a)

Values from fits to the spectral lines, numbers in parenthesis indicate 1σ uncertainties from these fits.

^(b)

Velocity shift of line center relative to z = 0.010411.

^(c)

FWHM of lines.

^(d)

Inferred velocity width is based on the instrument resolution assuming a sinc profile, only listed for partially resolved lines.

^(e)

Value of the fitted baseline at the line center.

^(f)

Undetected, upper limit is 1σ value.

^(g)

Detected with the spectrometer long wavelength array, due to the larger beam size this line might be contaminated by flux from the other components of Arp 299.
