Description

We present gas-phasemetallicity and ionization parameter maps of 25 star-forming face-on spiral galaxies from the SAMI Galaxy Survey Data Release 1. Self-consistent metallicity and ionization parameter maps are calculated simultaneously through an iterative process to account for the interdependence of the strong emission line diagnostics involving ([O II]+[O III])/Hβ (R23) and [O III]/[O II](O32). The maps are created on a spaxel-by-spaxel basis because HII regions are not resolved at the SAMI...[Show more]
