Notes.
From Spezzi et al. (2008).
From Alcalá et al. (2008).
Coordinates are taken from the PACS-70 μm map. For IRAS 12589-7646, Sz 52, and STc2d J130529.0-774140 coordinates from the PACS-100 μm map are reported.
Angular distance between the HGBS coordinates and the coordinates reported in Spezzi et al. (2008) and Alcalá et al. (2008).
The reported uncertainties are flux-extraction errors from getsources. The absolute calibration errors for PACS and SPIRE are 5% and 7%, respectively (see PACS and SPIRE observer manuals).
From Lehtinen et al. (2005).
