Notes. Column OBSID reports the Observational Identifier which specifies an observation in the Herschel Science Archive. Each field was observed twice along two almost orthogonal directions to better remove the instrumental 1/f noise. Date refers to the start of the observation; OD is the operational day (OD 1 is 14 May 2009). Centre gives the central coordinates of the map. The Observing mode column reports Parallel, for PACS and SPIRE data obtained in parallel mode, or PACS for data obtained with PACS only. PACS bands column reports the effective wavelength of the selected PACS filters. Speed is the scanning velocity of the telescope.
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.
