Fig. 8

Relative contributions of CO (red), [O i] (green), OH (yellow) and H2O (blue) to the total far-IR gas cooling integrated over the entire PACS array are shown from left to right horizontally for each source. The objects are in the sequence of decreasing total gas far-IR cooling, LFIR. Note that OH cooling is not available for BHR71 and Ser SMM4 and not measured in NGC 1333-I2A. Water cooling is not calculated for TMC1A.
