- Abstract
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.
