Notes. With ‘N.maps’, ‘Obs. time’, ‘Freq.’ and ‘HPBW’, we indicate the number of maps, the total observation time (including overheads), the central frequency and the half-power beam width. A single map is intended as a complete scan (RA or Dec) on the source. We also report the calibration errors and the feed channels (indicated with the feed number and ‘L’ and ‘R’ for the left and right polarization channels) discarded from data analysis (due to Low Noise Amplifiers problems).
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.
