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.

    The abundance of galaxy clusters with mass and redshift is a wellknown cosmological probe. The cluster mass is a key parameter for studies that aim to constrain cosmological parameters using galaxy clusters, making it critical to understand and properly account for the errors in its estimates. Subsequently, it becomes important to correctly
