Comparison of CO v = 1-0 5 μm emission toward several low-mass protostars. L1448 and SMM3 are Class 0 protostars, B1-a-NS is a Class I source, and the spectrum of NGC 1333 IRAS4B is taken at a shock knot position well off source (see Fig. 20). The bottom panel shows an optically thick CO model spectrum at T =1500 K.
