Notes. The quoted errors indicate the uncertainty on the average, not the intrinsic spread of the population. These uncertainties are derived through bootstrapping half of the full sample, recomputing all quantities for each bootstrap realization separately, and then measuring the standard deviation among all realizations. The gas-to-dust ratio is randomized within the allowed statistical uncertainty (Eq. (7)). The resulting values are then divided by 
to take into account that only half of the initial sample was used in each bootstrap realization.
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.
