Data (left) shown in comparison to models at distances of 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 kpc (left to right) showing the quasi-perpendicular (top) and quasi-parallel (bottom) CRE acceleration case for each SNR in the sample with a double limb. The set of best-fitting models, based on the visual appearance of the angle is highlighted with an orange box. In some cases the model is undefined at a location and so the model image show a blank. Where a published value for the distance is available, the range is indicated by an arrow above the models (references for these distances are summarized in Table 1).
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.
