Description
This paper presents a self-consistent method to determine abundance and
evolutionary status for giant H II regions (GHR) as well as the nominal
temperature of the ionizing cluster and the ionization parameter. This
new method makes it possible to recalibrate the empirical relationship
(R23, O/H) by Pagel et al (1979) up to abundances three times solar. The
effects of evolution of GHR on their observed spectra are explained in
terms of the cooling down of the ionizing population, and some
evolutionary tracks are presented.
