The Old Halo metallicity gradient: the trace of a self-enrichment process

Figure 2.

Comparison between 2 theoretical [Fe/H] vs logD relationships and the metallicity radial distribution function of the OH+noHBR groups. The plain and dashed curves represent the self-enrichment model combined with, respectively, the Murray & Lin (1992) and the Fall & Rees (1985) pressure profiles. GC symbols are identical as in Fig. 1
