Notes. (a) Typical noise of the data with the smoothed beam. Due to residual side lobes, the noise can be higher in areas round strong sources. (b) Noise of the line data is measured in the line free channels. (c)The OH line at 1667 MHz is observed for l = 29.2°−31.5°,  37.9°−47.9°, and 51.1°−67.0°. (d) RRL images were produced by smoothing and stacking all available RRL images. (e) Each continuum band has a bandwidth of 128 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.
