CO 3−2 spectra with selected integration limits indicated, except for Ced110 IRS4, BHR71, and DK Cha where CO 6−5 was used. Each panel presents these limits for each source. The black spectrum at the bottom is taken from a clean position representative for the envelope emission. The blue spectrum at the middle is the representative spectrum from the blue outflow lobe, and red spectrum at the top is the representative spectrum from the red outflow lobe. Each panel shows five vertical lines, these are V_LSR (black dashed line), V_out,blue (dot-dash blue line), V_in,blue (dashed blue line), V_in,red (dashed red line), and V_out,red (dot-dash red line).
