General Description

• This program is a deep multi-filter survey of the star forming region
   ChaI. 
  Run A, carried out with VIMOS, is the optical part of the survey using the
  filters I and z. (The near-infrared part is carried out with SOFI at NTT in
  run B.) We intend to observe four fields around the main cores of the
  ChaI region. For each field, we have created one OB, which contains all 
  observations for this field, i.e. a sequence of 10 long exposures in I and z 
  plus short exposures in both filters. The long exposures are carried out in 
  a small-scale dither pattern with 10" stepsize. 
  
  For each field and thus OB, we provide two finding charts: 
  a) Generated with the GuideCam software and based on optical images. Shows the 
  position of the guide probe and the guide star as well as the field of view. 
  b) A 5' 2MASS J-band image of the central part of the field. 
  Please note: The fields contain dark clouds. Therefore, optical images look
  very different from near-infrared images. In I- and z-band, the images will be
  more comparable to the 2MASS J-band.

Waiver Requests

• The waiver 078.C-0049A.01.WAV has been submitted on Jul 25 and granted
   on July 26. According
  to the waiver request, we are allowed to define OBs which have need up to 1.5 hours
   for 
  execution. This allows us to carry out all observations for a particular field in
   the same 
  OB, and thus in the same observing night, which avoids calibration issues in the
   photometry.

Critical Observing Condition Constraints

• Conditions should be clear, seeing less than 1.2".

Time-Critical Aspects

• No time critical aspects.

Special Execution Requirements

• No special execution requirements.

Special Calibration Information

• No special calibration required. We need bias, flatfield plus photometric
  standard stars according to the VIMOS calibration plan.

ToO Information

• N.A.

ToO Activators List

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 ?

• 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
