Notes. Columns (1–2): The size of the beam in angular and linear scales (adopting a distance of 4.75 Mpc). (3): The channel width, i.e. spectral resolution. (4–11): We quote the quantities for the sight line with the highest H I integrated intensities, i.e. for an aperture of 21″ ≈ 500 pc (see Table 4 for the mean, the 16th and 84th percentiles of some of these quantities): (4): Integrated intensity. (5): Uncertainty of integrated intensity (6): Signal to noise. (7): Peak temperature of the spectrum. (8): Root mean square (rms) noise. (9): Line of sight velocity, i.e. first-moment. (10): Uncertainty of the first-moment. (11): Ratio of IHI with FUV which results in units of K km s−1/(mJy arcsec−2). These are GALEX FUV observations that have been published in Bigiel et al. (2010a).
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.
