Notes.

(a)

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.

(b)

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.

(c)

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.
