Notes.The flux density (in erg s-1 cm-2) is given for the v = 1−0 S(1) line at 2.1218 μm, and flux ratios with respect to this line are given for the other lines. The third last column gives the estimated excitation temperatures Tex, the second last gives the estimated extinction (AV), and the last column gives the calculated ortho-to-para ratio o/p for the v = 1 vibrational level.
