Notes. Column (1): molecular tracer. Column (2): array configurations; “Comb.” stands for the combined imaging of the Compact and VEX data. Columns (3)–(5): image weighting, synthesized beam, and position angle (east of north) of each map. Column (6): 1σ rms of the map. Column (7): integrated velocity ranges (see Sect. 3.1). Columns (8)–(9): for maps of dust emission and lines measured within the bulk emission (Sect. 3.1), the peak position was derived by an elliptical Gaussian fitting (with fitted errors). For those line maps integrated over the red- and blue-shifted emission, we give the position of the peak. Column (10): peak brightness derived by Gaussian fitting (with fitted errors). Column (11): total integrated flux of the emission within the 5σ contour level. Columns (12)–(13): deconvolved major, minor axes and position angle of the emission derived by Gaussian fitting.
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.
