Table 2:

Observed numbers of EMP, CEMP, CNEMP and NEMP stars from the SAGA database for our various selection criteria.

The first line of data counts only stars which have a  measurement. The second line of data additionally counts stars without measured as EMPs, i.e. it is assumed that for these stars. In the next four lines stars with both measured C and N are used to count (C)NEMP stars while stars with C measured count the CEMP stars.
Also shown are estimates of the CEMP/EMP ratio from Cohen et al. (2005), Frebel et al. (2006) and Lucatello et al. (2006).
