General Description

• We wish to observe faint emission lines of circumstellar gas disks with
  long slit spectroscopy in 4 well-known Beta Pic-like disks.
  We use the same technique as the one used by Brandeker et al. 2004
  (A&A 413, 681).
  
  The stars are relatively bright (magnitudes from 4.8 to 7.0).
  
  The slits should be positioned centered onto the star in few OBs 
  (OB named "star-slit-1" and "star-slit-2")
  with short exposure time to avoid saturation.
  
  In other OB (OB named "star-slit-n" with n>=3), the slit is moved
  by a distance from 1.0 to 3.2 arcsec away from the star 
  in a direction perpendicular to the slit orientation.
  In these last cases, exposures times (about 700s) must avoid saturation:
  this should be the case assuming that the scaterred light with the slit away from
   the star
  is at least 10 to 40 times fainter than the light with the slit on the star.
  
  The slit positions are summarized in finding charts.
  The keyword derotation mode is set to 'SKY' and the Atmospheric Dispersion 
  Corrector (ADC) to 'AUTO' to allow the PA keyword to describe the slit orientation
   
  on the sky according to the finding charts.
  
  The execution of various OBs is independent and there should not be 
  any time link between observations.
