Scientific paper
Equivalent widths and relative intensities of emission lines in the red
spectral region have been determined for 49 galaxies exhibiting
emission, on the basis of spectrograms obtained with the 125-cm
reflector of the Crimean station, Shternberg Astronomical Institute. The
electron density and the abundance of several ions are estimated.
