Notes. Wavelengths and wave numbers are mean values of the clusters and the errors are standard deviations of the clusters. Energy differences with respect to the query are also given as Ediff. The vacuum-to-air-conversion formula of Morton (1991) was used to calculate the air wavelengths, λair. The strength ratios, I, are the median values of σS/σQ with the standard deviation as errors, and r denotes the Pearson correlation coefficient. Family members are divided in two quality groups: 1 and 2. Quality 1 implies that membership is certain because of tight strength correlations and strong profile correlations. Quality 2 indicates a weaker strength correlation, but still strong profile similarities. The quality flags are a subjective rating of the correlation. If, for example, two DIBs have the same distinct substructure, they can be rated quality 1, even if the Pearson coefficient is not as high as for some quality 2 DIBs.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
