General Description

• The goal of this program is to measure the central velocity dispersion
   of galaxies lensing quasars from the COSMOGRAIL program.
  
  We use FORS2 with the standard resolution collimator and the *1x1* binning for all
   5 targets, i.e. this is a non-standard mode.
  
  MXU is used, with one slit on the target and others on PSF stars. Good centering
   of all these objects is important. 
  Note that for WFI2033-47 the slit used for the science target is aligned on two
   of the quasar images and does not pass
  by the center of the lesing galaxy. This is on purpose, to facilitate the spatial
   deblending using deconvolution.
  
  
  We need deep spectra, so better finishing one object than starting all. These data
   are long awaited, doing
  even a few objects completely will be useful and published. 
  
  We add radial velocity standards and spectrophotometric standard stars. If data
   are taken for our program
  at all, please execute as well these calibration OBs. 
  
  Note that these are NOT mandatory if the sky flats are taken. We would need 1 sky
  flat for each of the 5 mask in order to get the instrument response (in velocity
   084.A-0337B.03.WAV). 
  We have provided 5 OBs, following instructions by ESO, to do these flats. Their
   names starts with SkyFLat followed
  by the object name. 
  
  Please do not move the telescope after the last image through slit. This will help
   measuring the slit clipping of 
  the object. If the telescope is moved after the through-slit image, please take
   another one before the science
  exposure starts.
