Notes. Average line ratios were calculated from the average line fluxes.

(a)

Line centers are measured in the barycentric and radial velocity corrected spectra. Their value is the center and 3σ error of the Gaussian fit to the line.

(b)

Integrated flux and FWHM of the Gaussian fit and 1σ error; upper limits of the integrated line flux are 3σ assuming a line width of 10 km s-1; the error in the average is the maximum between the standard error of the mean and .

(c)

Detection but Gaussian fit not possible;

(d)

No meaningful FWHM due to the low sigma detection;

(e)

Detected but severely affected by the atmospheric transmission.
