Comparison between NIBLES and literature values for central H i line velocities, VH I, and W50 line widths. Only sources matched in H i velocity and in line width are plotted (see Sect. 4.6). Top panels: comparison with data from the α.40 ALFALFA catalog (Haynes et al. 2011); lower panels: comparison with HIPASS data ((Meyer et al. 2004; Wong et al. 2006). Left-hand panels: W50 line widths. Literature values as a function of NIBLES widths (in km s-1). The solid line marked with “1:1” indicates equality between both scales and was only added to guide the eye. Right-hand panels: central H i line velocity. Difference between VH I (in km s-1) measured at the NRT for NIBLES and literature values as a function of NIBLES line velocity (in km s-1). The horizontal lines indicates the mean velocity differences.

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.
