General Description

In this observing run long-slit spectroscopy of 19 young stellar object
 candidates in the Chamaeleon II star forming will be performed using EMMI@NTT. Grating
 D#7 was chosen in order to achieve a resolving power of the order of 2500, which
 is suitable for the detection of the LiI(6708A) absorption line and for spectral
 type classification purposes.
The observations must be performed in the red-arm configuration (REMD), with central
 wavelength 645 nm. The R-band magnitudes of the candidates range between 13 and
 18 mag. The exposure time must be 10 min for the bright objects in the sample (13
