Fig. 18


Visualization of the measured and cataloged sources (Sect. 2.7). The field of Fig. 2 is shown at 70, 100, 160, 250, 350, 500 μm (left to right, top to bottom) with the extraction ellipses (FWHM) of the measurable sources (F   P > σ   P and F   T > σ   T) overlaid on top of the observed images ℐλO. The default condition, that a tentative source must be detected in at least two bands, was used. Only the protostellar cores are visible at 70 and 100 μm, whereas at 160 μm cold starless cores starts to appear, becoming clearly visible in the SPIRE bands. For better visibility, the values displayed in the panels are somewhat limited in range; the color coding is a function of the square root of intensity in MJy/sr.

This figure is made of several images, please see below:
