General Description

• This is a FORS2 MXU observation of the outer halo of NGC 4696, in two
   fields EAST and SOUTH. We use a mask of parallel slits, plus the narrow band filter
   [OIII]/3000+51 and Grism-600B+22 to detect the [OIII]lambda 5007 AA emission line
   from Planetary Nebulae associated with the light.
  
  This is a blind search technique. The mask has 5 to 7 holes at the field star positions
   so that the mask can be aligned correctly during service mode observations. Once
   the mask is aligned with these positions a sequence of offsets in Right Ascesion
   can be performed. This is detailed in the Special Execution Requirements.
  
  Please execute all the OBs for one field before going to the next.

Waiver Requests

• Waiver Request 082.A-0255A.01.WAV
  We submitted a waiver request to be able to use a non-standard combination of GRISM
   and filter for FORS2-MXU run. We need to use the grism GRISM600B+22 and the narrow
   [OIII] filter [OIII]/3000+51 jointly. Waiver granted.

Critical Observing Condition Constraints

• seeing: <0".8 - gray moon nights

Time-Critical Aspects

• None

Special Execution Requirements

• Please execute all the OBs for the EAST field before moving to the SOUTH
   field.
  
  Each OB of the EAST field has the same acquisition and through-slit templates. Once
   the through-slit image has been succesfully executed, please execute the offset
   in Right Ascension, according to the OB name, as listed in the table below:
  
  	OB name				offset in arcsecond in the R.A. direction
  
  sciMXU_N4696_E0				 0".0
     "     "  _E01			 1".3
     "     "  _E02			 2".6
     "     "  _E03			 3".9
     "     "  _E04			 5".2
     "     "  _E05			 6".5
     "     "  _E06			 7".8
     "     "  _E07			 9".1
     "     "  _E08			10".4
     "     "  _E09			11".7
     "     "  _E10			13".0
     "     "  _E11			14".3
  
  Each OB has one finding chart showing the whole instrument field of view. We also
   added two zoomed images of the field where are shown the positions of the stars
   that have to be used for a correct alignent of the mask during the through-slit
   image.

  Each OB of the SOUTH field has the same acquisition and through-slit templates.
   Once the through-slit image has been succesfully executed, please execute the offset

Special Calibration Information

• We need standard calibration. Please be aware that we are using the [OIII]/3000+51
   narrow band filter, so the arclamp exposures and the flat fields need longer exposure
   time to reach enough counts.
  For the arclamp we need at least two bright emission lines for wavelength calibration.
  The specto-photometric standard star calibration forseen in the ESO standard calibration
   plan are adequate for our needs.
