Description
We have measured absolute fluxes of the lines present in a high dispersion short wavelength exposure of NGC 3918. Amongst the measured lines we have several density dependent multiplets and the C IV and N V resonance doublets. The mean electron density derived is of 5x103 cm-3, in agreement with previous determinations. We find an anomalous value of 1.2+-0.1 for the ratio of lambda lambda 1239/1243 of N V. We discuss its implications. (author)
