Notes. Limitations to use the lines ratios can be due to blends, telluric contamination, or if the lines have very different wavelengths and underlying continua. The uncertainty levels are taken from the NIST database and reflect the uncertainty in the atomic parameters for the most uncertain line. For lines with errors >40%, the theoretical line ratio is very uncertain, especially if the transition probabilities are similar.
