Estimated Total Execution Time (hours, including overheads)

• 6h

General Description

• The program consists of 2 parts:
  a) imaging in the Q2 filter. This is to be done with standard chop-and-nod as indicated
   in the templates with the object chopped on the detector!
  b) LR spectroscopy of the entire N-band (4 spectral settings) of 2 clusters in one
   slit. Again a standard chop-and-nod as indicated, with the object chopped on the
   slit.
  
  Acquisition science target & science observations: Q2-band imaging
  ------------------------------------------------------------------
  A blind preset will do. With the setup as indicated in the templates in nodding
   position A the 
  chopped image is off-detector. In Nod B chopping on the detector.
  
  Acquisition science target & science observations: N-band spectroscopy
  ----------------------------------------------------------------------------
  Acquire the object using the brightest peak. Nodding on the slit, 
  but the brightest MIR peak should not be in the centre of the slit but 
  offset (4.3 arcsec to the right on the acquisition screen), to avoid bad pixels.
  
  Finding charts
  --------------
  A large schale findingchart based on an ISAAC J-band image. Also included
  is a zoom-in on the cluster, this is a VISIR NeII image.

Waiver Requests

• A Waiver Request was submitted to allow for OBs longer than 1 hour. This
   request was granted May 30 by Monika Petr-Gotzens.
  Waiver-ID: 275.B-5016A.02

Critical Observing Condition Constraints

• Imaging: 
  A seeing of max 1.0 arcsec visual is acceptable.
  Sky transparancy: clear
  
  Spectroscopy: 
  To disentangle the two clusters a seeing of max 1.0 arcsec visual is acceptable.
  Sky transparancy: clear

Time-Critical Aspects

• none

Special Execution Requirements

• none
  This field has been observed with VISIR before (April 17 and 18 2005), finding a
   guide star wasn't a problem.

Special Calibration Information

• Standard calibration, please use an early type star for calibration.
