| Data-1 (continuum) | L25937 | 2011 May 4 | 23:00:01.5 | 18 | 5 | 48.768 | 325 |
| Data-1 (RRL) | L25937 | 2011 May 4 | 23:00:01.5 | 18 | 5 | 0.762 | 5.1 |
| Data-2 (RRL) | L31848 | 2011 Oct. 15 | 12:00:02.5 | 15 | 5 | 3.1 | 21 |
Notes.Raw visibilities from Data-1 were processed twice to create two separate intermediate data sets for i) continuum imaging and ii) the RRL detections (see Sect. 2). The velocity resolutions were computed at 45 MHz.
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.
