Scientific paper

A stellar population synthesis model for the UV spectrum of the peculiar galaxy NGC 1672 was developed using a set of 170 stellar spectra selected from the IUE Atlas Spectral Library (Heck, 1984). The observed fluxes were converted to absolute fluxes and were weighted according to the constructed HR diagram. A reddening law similar to the one derived by Nandy et al. (1981) for the 30 Dor region was applied to the computed cluster spectrum. A good match was found between the observed and predicted spectra.
