Notes. (a) The parameters on this row were derived from a Gaussian fit to the blueshifted peak. (b) The parameters on this row were derived from a Gaussian fit to the redshifted peak. (c) These upper limits were calculated by using the quoted 3σ intensity upper limit and the FWHM of the N2H+(3−2) line (0.67 ± 0.27 km s−1) detected by Miettinen et al. (2012).
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.
