CNO NH3360 THIS WORK • They can help enormously to fine tune the previous scenarios • C & N are necessary to calculate O abundance • Main contributors to the global metallicity (not studied in detailed) • Sánchez-Blázquez et al. 2003 → CN depends on environment d=–0.029±0.006 d=–0.010±0.003 • CN depends in a complex way on C, N and O Coma Field • To disentangle the CNO contributions by NH3360 (‘pure’ N)
