High-resolution (~18″) column density map of Orion B, derived from SPIRE and PACS observations. The positions of the 1768 identified starless cores (green triangles), 490 robust prestellar cores (blue triangles), and 76 embedded protostellar cores (red symbols) are overplotted. The vast majority of the cores lie in high column density areas. The white declination line at Dec₂₀₀₀ = 1° 31′ 55″ marks the lower boundary of the northern region where cores may be associated with the Barnard’s Loop and at a more uncertain distance (d ~ 170–400 pc). See Sects. 1 and 3.5.2 for details.
