H Ii Regions, Abundances

Scientific paper

[SII] electron densities, [OII] and [OIII] electron temperatures and oxygen chemical abundances for a sample of HII regions compiled in the paper. Electron densities have been calculated from the I(6717)/I(6731) quotient. When these lines have not been available, in order to calculate te[OII] it has been supposed a value of ne=100cm-3. te[OII] have been calculated from the I(3727)/I(7325) quotient. When the auroral line has not been available, it has been used photoionization models to deduce it from te(OIII) taking into account the density value (see Perez-Montero & Diaz, 2003MNRAS.346..105P).
