Notes. All quantities were computed using maps at 30 resolution. The map of NH is a combination of H i (21 cm LAB data) and CO (Planck) assuming XCO = 2 × 1020 H2 cm-2 K-1 km-1 s following Bolatto et al. (2013). This estimate of NH is a lower limit as it does not account for the ionized gas and the molecular gas not detected via CO. See Table 3 for the definitions of each mask.

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.
