Table 1

Star ID, effective temperature, surface gravity, model metallicity, microturbulence, radial velocity, abundances derived from Fe I and Fe II lines, Na, and O abundances and their associated root mean square error (rms) for each of the M 15 stars analysed here as determined in C09.

Table 3

Hyperfine structure decomposition based on atomic information obtained from the associated references for the Ba II (Rutten 1978; Davidson et al. 1992), La II (Lawler et al. 2001a) and Eu II (Lawler et al. 2001b) spectral lines used in the spectrum synthesis of the M 15 giant stars.

Table 11

Chemical abundances, uncertainties and number of lines measured here for the sample of 63 M 15 giant stars. The C09 stellar parameters, ξW13 and measured S/N are also listed.
