  Standard spectroscopic program aiming at detecting the luminosity 
threshold for the appearance of the Tc lines in 7 C- (at 5924A) and 
6 M-stars (at 4238-4262-4297A) in the SMC.

  Radial velocity standard stars need also to be observed: one, on 
each night a C-star is observed. If more than one C-star is observed 
on given night, please observe two different radial velocity 
standard stars (as provided by user: HD 29 and HD 693). 

  Given the faintness of some stars, exposure times up to 1h30m  
are needed to get an acceptable S/N around 4250A (for M stars) or 
5900 A (for C stars) and have been allowed under the agreement that 
degraded atmospheric conditions will be tolerated after the first hour 
of exposure. Change of targets wrt to Phase1 approved by VISAS.
