From: The 626M24 dataset of validated transitions and empirical rovibrational energy levels of 16O12C16O
Uncertainties of the experimental rovibrational line-center positions available for the 16O12C16O molecule, as a function of the transition wavenumber (note the logarithmic scale of the vertical axis). If multiple measurements are available for the same line, the most accurate transition is chosen.
