References. The references listed in the last column are for molecular measurements. When two references are listed, they correspond to CO then H2, in this order. (1) This work; (2) Noterdaeme et al. (2011); (3) Noterdaeme et al. (2010); (4) Srianand et al. (2008); (5) Noterdaeme et al. (2009); (6) Klimenko et al. (2016); (7) Jorgenson et al. (2010); (8) Noterdaeme et al. (2007). Unless already available from the literature, C I column densities were obtained through the apparent optical depth method.
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.
