Estimated Total Execution Time (hours, including overheads)

• 36.417

General Description

• This program is set to obtain a long 18h integration time in each of LRBLUE
   and LRRED, through the same mask. This will be repeated for 3 different VIMOS pointings
   to complete the LP. Each 18h integration is cut in 11 OBs, with the objects moved
   along the slit at positions 0, 0.3, 0.6, 0.9, 1.2, 1.5, -0.3, -0.6, -0.9, -1.2,
   -1.5, respectively. Each OB includes 4 exposures of 1473 sec, and one wavelength/arc
   calibration, for a total execution time of 2h08m. For P77, 36.417h are scheduled
   out of 37h allocated, this allows to do 11 OBs (18h integration) for one mask with
   LRBLUE, and another 6 OBs (9.8h integration) for the same mask with LRRED.

Waiver Requests

• The following waivers have been submitted:
  1. Work at rotator on sky = 0 (as for pre-images): this has been approved 31 July
   2006
  2. Use OBs longer than 1h: this has been approved 31 July 2006
  3. Do only a couple of wavelength/arc calibration for each sequence of 11 identical
   OBs: this has unfortunately been refused. We do not think it is necessary to obtain
   11 times the same information,
  as wavelength calibration is systematically adjusted on sky lines positions by our
   VIPGI pipeline. 
  4. Allow to take exposures up to airmass = 1.5, this has been approved 2 Aug. 2006

Critical Observing Condition Constraints

• We have set the following:
  - Seeing better than 1.2
  - Sky photometric (very deep observations requiring best transparency)
  - Moon illumination less than 0.5 (quarter moon)
  - Distance from the moon larger than 60 deg
  - Airmass less than 1.5

Pre-imaging Requirements

• ---(Empty)---

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 ?

• N/A

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 ?

• N/A

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
