Estimated Total Execution Time (hours, including overheads)

• 0.3

General Description

• The program is completed in principle but one spectroscpic observation,
   which could not be completed due to some problems with one pre-imaging OB. We were
   advised to resubmit an OB for the preimaging which is included in this observation
   request. The total execution time required is 24 minutes.
  
  
  The general aim of the program is an in-depth study of the dynamics and galaxy population
   of massive X-ray selected galaxy clusters. This pre-imaging observation is in preparation
   of a comprehensive spectroscopic study of one cluster field with VIMOS spectroscopy.
   With this VIMOS mask we aim to obtain about 400 galaxy spectra of this cluster,
   including background objects.
  
  We hope that this pre-imaging observations can be done fast enough so that it can
   be followed up by spectroscopy while this object is still visible in this semester.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• none

Time-Critical Aspects

• The monitoring program (run G-b) needs regular exposures of the central
   parts of
  the cluster as defined in the OBs with abut a three day tolerance for the date.
  In case the exposure cannot be made within the time frame, an additional exposure
  covering the longer gaps would always be extremely valuable.

Is this a Pre-imaging run ?

• true

Pre-imaging Requirements

• Source of preimaging:
  
  run G-part 2 is a preimaging run. Please make the preimaging observations
  early enough that spectroscopic observations can be defined and executed
  in the same period.

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 ?

• YES

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 ?

• N/A

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
