$^{\dagger}$ Intensities measured in units of 10$^{-14}$~erg~cm$^{-2}$~s$^{-1}$. No correction for extinction is necessary.  The determination of I/H$\beta$ is discussed in the~text. \\
The measured line intensity is  given in Col.~3. The last column gives the ratio of the line intensity to H$\beta$(=100).
