The ISO Galactic metallicity gradient revisited.

GIVEON U., MORISSET C. and STERNBERG A.

Abstract (from CDS):

Two independent groups (Giveon et al., 2002ApJ...566..880G; Martin-Hernandez et al., 2002A&A...381..606M) have recently investigated the Galactic metallicty gradient as probed by ISO observations of mid-infrared emission-lines from HII regions. We show that the different gradients inferred by the two groups are due to differing source selection and differing extinction corrections. We show that both data sets in fact provide consistent results if identical assumptions are made in the analysis. We present a consistent set of gradients in which we account for extinction and variation in electron temperature across the Galactic disk.
