Notes. Properties of SWAN datasets: For the combined NOEMA+30m data, the NOEMA data, and the 30m data we list the molecular emission line (1), its rest frequency (2), the native beam size (3), and the beam position angle (4), as well as the peak temperature, Tpeak, and typical rms for different spectral resolutions (10 km s−1: (5), (6); 5 km s−1: (7), (8); 2.5 km s−1: (9), (10), 1 km s−1: (11), (12)). Tpeak refers to the peak intensity of the brightest pixel in the data cube. The rms is the average rms of the first and last five channels, which are free of emission. For all datasets, both peak intensity and rms were calculated inside the area covered by the mosaic (see Fig. 1). In this area, the sensitivity is comparably constant and to avoid the increased noise towards the edges of the mosaic. The 30m data refers to combined datasets of archival EMPIRE and CLAWS data and the newly obtained IRAM 30m observations.
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.
