Estimated Total Execution Time (hours, including overheads)

• 28.49 hours

General Description

• Our programme consists of 4 VIMOS fields in a ~ 30' x 30' region around
   a z=0.8 galaxy cluster.
  An overall finding chart showing these 4 fields can be found at
  http://www.mpe.mpg.de/~milvang/tmp/cl1216_VIMOS_footprints3.ps.gz
  
  For each field we have 4 identical OBs each doing 1 hour 7.5 min of integration
   (split in
  5 x 13.5 min), giving a total exposure time of 4.5 hour per field. Each OB has an
   execution
  time of 1 hour 43.5 min, for which we have a phase 2 waiver. 
  
  Our targets have total I-band magnitude in the range 19-22. In each quadrant we
   have 2-3
  reference "slits" (4" x 4" boxes) with stars that were bright but unsaturated in
   our
  100 sec R-band pre-images. In each OB we give the exact number of reference slits
   to look for.
  
  We take 5 exposures (of 13.5 min) at offset positions -1.6 +1.6 -0.8 +0.8 0 arcsec,
   where 0 is the preset position, to be able to correct for fringing.
  
  The OBs should be observed within 2 hours of culmination. This corresponds to an
   airmass below 1.17, but we had to enter 1.1 in the constraints set, since only 1
   decimal was allowed.
  
  We have two night time calibration OBs, called CAL_*_UseThisOne, which each observes
   a hot star
  (spectral type O or B).

Waiver Requests

• We submitted a waiver on 8 Mar 2005, and it was approved on 9 Mar 2005;
  it's reference number is 075.A-0649B.01.
  
  The waiver allows us to have OBs with an execution time of 1 hour 43.5 min.

Do all your OBs comply with the instrument-specific requirements listed
 on the instrument-specific Phase 2 web page ?

• YES

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
 Category for each Observing Template ?

• N/A

Do all your finding charts comply with both the general and instrument-specific
 Phase 2 Web Pages ?

• YES

If you submitted OBs for standard stars, did you specify the magnitude
 and spectral type of all standard stars in the OBs ?

• YES

Have you included OBs for any calibrations that you need but which are
 not part of the Calibration Plan ?

• YES

If you are observing Moving Targets, have you attached suitable ephemeris
 files to your OBs?

• N/A

If you have preferences which OBs should be executed first, did you make
 use of the User Priority field in the OBs ?

• YES

If this is a run that requires coordinated observations with other facilities,
 did you give proper instructions in the Time-Critical Aspects Section ?

• N/A

Did you specify suitable guide stars for all your OBs using Guidecam
 ?

• YES

Did you check that the chosen guide stars are suitable for all the offset
 positions and that they do not produce unacceptable vignetting of the field of view
 ?

• YES
