Left: sample of intensity radial profiles illustrating the different cases encountered in the analysis of the 1670 GHz line PACS data: outflow with extended emission (BHR71-R), outflow with compact emission (HH1), and outflow with emission that is too weak to allow a meaningful fit (I04166-B). Blue dots are PACS data and red dashed lines are Gaussian fits. Right: comparison between the size (uncorrected for the telescope beam) and intensity of the H2O-emitting region as determined from the Gaussian fits illustrated in the left panel. The star symbols indicate data from maps centered at a YSO position and the horizontal dotted line indicates the telescope FWHM at 1670 GHz (13′′).
