Notes. (†) Since we are currently not studying the detailed maser variability, observations carried out on multiple dates were averaged in the spectra presented in Fig. C.1 and throughout the paper. If wanted, date-separated spectra can be provided by us or retrieved from the ESO archive. (‡) Maser emission not detected on this date. Data not combined with original survey data.
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.
