Reference. PN(7–9 kpc) average abundance of PNe within 7 to 9 kpc from the Galactic centre Pottasch & Bernard-Salas (2010); vis(bulge) average PNe abundance in the bulge as determined using only visual spectra Chiappini et al. (2009); solar abundance Asplund et al. (2009); H ii(0–4 kpc) average abundance of H ii regions in the Galactic bulge Martín-Hernández et al. (2003), and Rudolph et al. (2006).
