Example of association between a Herschel target and an object with known distance in the case of the field G202.02+2.85 apparently connected with the stellar open cluster NGC 2264. The colour scale shows the relative intensity in the WISE 12 μm band. White and red contours are 0 and 100 MJy intensity levels from the Herschel 250 μm band and emphasise the map edges and the submillimetre mapped filament, respectively. The purple stars are those associated with NGC 2264 according to the SIMBAD database.
