Abstrakt

We construct high-resolution column-density and effective-temperature

maps for the Pipe nebula region based on sub-mm/far-infrared and

near-infrared data. Based on these maps, we show that the slope of the

relation between column density and temperature can be used to

distinguish dense from diffuse regions in the cloud. Therefore,

temperature information could be employed in one of the criteria to

define cores in a physically motivated fashion.
