Abstract: | |||||||||||||||||||||
The total hydrogen column density map was derived using Herschel flux maps in the wavelength range from 160 to 500 micron and has a spatial resolution of 18.2 arcsec.
The molecular hydrogen column density map has been produced subtracting the HI component.
The kappa0 map is the dust absorption coefficient of the dust opacity model derived using HI data and the Herschel 250 micron map (SPIRE). The Xco conversion factor map has been derived using the molecular hydrogen column density map and the IRAM 30m CO map.
