Notes.
Observed equatorial coordinates (J2000) towards the target, i.e. the centre of the fitted point source, which refers to the primary α Cen A, except for Hi-GAL and APEX-SHeFI maps.
Offset of observed with respect to intended (= commanded) position. Except for SHeFI, coordinates are corrected for the stellar proper and orbital motions. Not applicable (na) to survey data.
According to the SPIRE manual, see http://herschel.esac.esa.int/Docs/SPIRE/html/, the average beam area is 423 arcsec2 at 250 μm, 751 arcsec2 at 350 μm and 1587 arcsec2 at 500 μm.
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.
