Originally published in 2014A&A...567A..55SAtmospheric parameters, radial velocities, lithium equivalent widths are products of the Gaia-ESO Survey that were used for our membership analysis of the 48 UVES targets observed in the Gamma Velorum fields. Also photometry from Jeffries et al. (2009MNRAS.393..538J) has been used. Iron abundances of these stars have been used to determine the metal content of the cluster. We also discussed the metallicity derived through the iron abundances of the 208 cluster members targeted with GIRAFFE and identified by Jeffries et al. (2014A&A...563A..94J). Stellar parameters of 39 stars targeted by both UVES and GIRAFFE have been used to check the quality of the data.
