3 Line identifications

These were made in the traditional way, paying attention to both wavelengths and line intensities within the multiplets. The identifications were made with the help of the table of Moore (1959); for Fe II we also used Johansson's (1978) compilation. In addition we have used the Meinel et al. (1969) catalogue, for lines which we could not identify (see notes to Table 2).

On our spectra are present 270 emission features. The complete list of identifications is given in Table 2. Parts of the spectrum are reproduced in Fig. 1.
