General Description

• Program 082.A-0278(A)
  This run is the pre-imaging in the R-filter of three fields targeted for 
  MXU spectroscopic observations containing a sample of early-type galaxies 
  at z~1.4.
  These galaxies have magnitudes R~24.5 (Vega), thus an exposure time of about
  30 minutes is required on each field to detect them at a S/N~8.
  To reach this magnitude with this exposure time, observations should be carried
   
  out under Clear sky transparency and no more than 10 day before the new moon 
  if possible. This run includes 3 OBs, one for each field.
  
  Each OB is composed by two templates: the acquisition template
  FORS2_img_acq  and the science template FORS2_img_obs_crsplit.
  The acquisition template rotates each field by the proper angle in order 
  to fit the galaxies within the effective area of FORS2 in MXU mode.
  We calculated the PA positive from North to Est and, according to the 
  definition of "Rotator on sky=-PA", we specified a negative value.
  
  The science template executes three exposures (Number of exposure per setup) 
  of about 10-11 minutes each, summing up to 30 minutes on each field. 
  No Tel. offsets between the three exposures are applied.

Is this a Pre-imaging run ?

• true

Pre-imaging Requirements

• Targets are as faint as R~24.5  (Vega), thus we believe that pre-imaging
  should be carried out under clear sky condition.
