Scientific paper

Radial velocities and spectral indices for 218 stars and brown dwarfs around {sigma} and {lambda} Orionis. Observations were obtained with the FLAMES/GIRAFFE multi-object spectrograph on ESO's VLT UT2 (Kueyen) telescope (programme ID 076.C_145). The equivalent width of the NaI 8200{AA} and the strength of the TiO 8442{AA} spectral features were measured from the median average spectrum. Radial velocities were measured by cross-correlation against a template spectrum of the brown dwarf star USco CTIO 055 at multiple epochs.
