$^{\dagger}$ Intensities measured in units of 10^-14 erg cm^-2 s^-1. The intensities below 19 $\mu$ m have been increased by a factor of 2.65 and those by a factor of 5.5 to bring them all to the same scale (see text).
(:) Indicates an uncertain value.
Note: The measured line intensity is given in Col. 3. The last column gives the ratio of the line intensity to H $\beta$ (=100).
