General Description

We will obtain Giraffe and UVES spectra of X-ray detected and undetected
 candidate members of a selected field in the rho Oph Star Forming Region. Our aim
 is determine radial velocities, metallicity, lithium abundances, Halpha and Ca II
 radiative losses in order to confirm cluster membership and investigate the origin
 of coronal and chromospheric emission in different type of young stars. We will
 use Giraffe with H665.0 and H875.7 and UVES with the 580nm and the 860nm setups.
 All OBs use the same fiber configuration. The Giraffe and UVES setups are H665.0
 and 580nm for the first 4 OBs (OPH_15_580_1, OPH_15_580_2, OPH_15_580_3, OPH_15_580_4)
 and H875.7, 860nm for the other 4 OBs (OPH_21_860_1, OPH_21_860_2, OPH_21_860_3,
 OPH_21_860_4)

The expected values of S/N per exposure with H665.0 and H875.7 for an R=17 star
 are 30 and
20, the expected value both with UVES 580nm and 860nm for a R=14 star is 50  

The configuration is valid for HA from -4.0h to 4.0h

The star selected as VLT guide star (marked with a diamond in the finding charts)
 has R=12.56

The four fiducial stars (marked with squares in the finding chart) have R=12.63,
 R=12.98, R=13.27, R=13.80
