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.
