ADC_Keywords: Clusters, globular ; Stars, giant ; Abundances Keywords: stars: abundances - stars: atmospheres - stars: Population II - globular clusters: general Abstract: We present abundances of Fe, Na and O for 1409 red giant stars in 15 galactic globular clusters (GCs), derived from the homogeneous analysis of high resolution FLAMES/GIRAFFE spectra. The program clusters cover a range in metallicity from [Fe/H]=-2.4dex to [Fe/H]=-0.4dex, with a wide variety of global parameters (morphology of the horizontal branch, mass, concentration, etc.). For all clusters we find the Na-O anticorrelation, classical signature of the operation of proton-capture reactions in H burning at high temperature in a previous generation of more massive stars now extinct. Using quantitative criteria (from the morphology and extension of the Na-O anticorrelation), we can define three different components of the stellar population in GCs. Description: Coordinates, magnitudes (B, V, K2mass), heliocentric RVG, atmospheric parameters, abundances of Fe, Na, O are presented for 15 of our sample of 19 galactic GCs. Observations were done using two GIRAFFE gratings, HR11 (for NaI 6154-6160Å lines) and HR13 (for [OI] 6300Å line). File Summary:
