Estimated Total Execution Time (hours, including overheads)

• 4 hours

General Description

• VIMOS-IFU observations of a giant elliptical lens galaxy. The aim of the
   observations is to obtain stellar kinematics and line-strengths, using V-band stellar
   absorbtion lines. The instrument mode is HR-BLUE, sampled with 0.67 arcsec fibres
   to maximise the field of view. A blank sky offset field is included in the first
   OB (see 'Special Execution Requirements').
  
  Since the program uses IFU mode, no guide star is specified.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• clear sky
  seeing < 1.5 arcsec (FWHM)
  airmass <=1.3
  dark sky (no moon)

Time-Critical Aspects

• None

Special Execution Requirements

• The target object fills the field, but approaches the sky surface brightness
   in the outer regions, making sky-subtraction important. For this reason, the first
   OB has a sky offset exposure of 15 minutes, offset (90",-90") from the science field,
   taken after the galaxy exposure (and associated calibrations). The attached calibration
   will be used for both galaxy and sky exposures in this OB.
  
  Since VIMOS is square, no particular position angle is required, and the default
   (aligned N-E) is acceptable.
  
  The target should be centered in the field as well as possible.
  
  Each OB has a small 'dither' offset, defined during acquisition, equivalent to 1.5
   fibers to allow oversampling and bad-pixel rejection. A larger spacing between dithers
   is also acceptable if recommended by ESO (e.g. if there is a 'bad region' larger
   than 1-2 neighbouring fibers), as long as the offsets are minimal and correspond
   to a non-integer number of fibers.
