Notes. The second column reports the spectral resolution, the third the parts of the CMD covered by the spectra, the fourth the S/N range of the data, the fifth the full spectral range (in A), the sixth the number of good targets for each dataset, the seventh and eighth the spectral range we used to measure C and N abundances respectively (in A).
