H₂ column density and dust colour temperature (T_C) maps of H-MM1 derived from Herschel-SPIRE HiRes data. The rectangle shows the area covered by the grid used for the line maps derived from the OTF observations. The circle shows the effective beam size (FWHM) of the SPIRE HiRes maps at 500 µm. The plus sign shows the location of the H₂ column density peak of the core, used as (0,0) in the molecular line maps.
