General Description

• This programme aims the full spectroscopic mapping of a sample of six
   nearby galaxies using the VIMOS IFU. 
  
  Given the size of the targets, the number of 54"x54" VIMOS-IFU pointings required
   ranges between 6 and 9. Since only a maximuum of 3 pointings can be done in a single
   OB (for a OB duration of ~1h15min, thanks to a Waiver) there are 2 or 3 OBs per
   galaxy. All OBs (except IFU_NGC_5669_3) include the observation of 3 pointings/offsets.
   At each pointing/offset, we obtain 3 exposures (for CR rejection) of 300s each.
   In the case of IFU_NGC_5669_3, only 2 pointings/offsets are observed, each with
   4 360s-long exposures.
  
  We have set three different priorities, (1) for the highest priority targets (NGC_5669,
   NGC_4496A, NGC_4941), (2) for medium priority ones (NGC_4517, NGC_4698), and (3)
   for low priority one (NGC_5363).
  
  Note that, following the VIMOS-specific rules for finding charts, these are 5 arcmin
   x 5 arcmin in size and show the FOV of the VIMOS IFU (magnification 0.67") with
   the distance of each pointing to a nearby bright star (identified by a red circle).
   In the case of the IFU_NGC_4517_* OBs the finding chart is 10 arcmin x 10 arcmin
   in size given that this galaxy is significantly larger than 5 arcmin along its major
   axis. The Preset position in the OBs corresponds to the center of the corresponding
   finding chart.

Waiver Requests

• A waiver for this programme, asking for execution times longer than 1
   hour, was submitted and approved on February 11th 2008.

Critical Observing Condition Constraints

• There are no constraints regarding the seeing. 
  Observations should be carried out with a lunar illumination <0.5 and a moon
   angular distance >30 dg.
  The maximuum airmass should be 2.
  The observing constraint regarding sky trasparency has been set to "Clear".

Time-Critical Aspects

• The galaxies are accesible from Paranal with airmass <2 from April
   through mid-July, although the best months are April and May.

Special Execution Requirements

• Preference should be given to the completion of all the OBs on a given
   target before proceeding with another target.
