General Description

• This run observes 2 different binary brown dwarfs in 2 different spectroscopical
   OBs.
   
  Only for OB 281933 concerning 2MASSJ 1534-2952: If you can orient the binary components
   along the finer sampled X-axis without losing the TTS due to the limited range of
   the field selector, please try to do this. 
  
  In addition we attached valuable magnified Finding Charts for both OBs with the
   clearly resolved binary. 
  In both OBs the science object should be clearly visible during acquisition and
   should be centered in the array. Since we chose the 25mas resolution scale only
   our target (and therefore = the brightest target) will be visisble in the FoV of
   0.8\" x 0.8\"
  
    OB names		R (TTS)		target				separation	comments
    -----------------------------------------------------------------------------------------------------	
    2MASSJ1534-2952	16.32		K~ 14.6				30.88 arcsec
    EpsIndiBC		15.52		K~ 13.53 		 	43.54 arcsec
  
  we know, that the TTS for EpsIndiBC has quite a large separationis and the AO correction
   might not be perfect, but its the only guide star in the permitted radius and the
   limiting magnitudes for R and B for a TTS. Since the science target is very interesting,
   its still worth trying. For the largest Finding Chart for EpsIndi we used also an
   2MASS K-band image from Epoch 2000. Due to the high proper motion of our target
   we calculated the predicted position for Epoch 2007.5 and added the position as
   a red dot.
  
  The OBs: For both targets, 2MASSJ1534-2952 and EpsIndiBab, the OBs contain 10 dither
   points in total (for each OB). 8 science dither points and 2 sky-dither points (one
   in the middle, one in the end). 
  The goal is to stack together all the science output of one OB to achieve the necessary
   S/N ratio for data reduction.

Critical Observing Condition Constraints

• Since the contrast and resolution are very dependent on the ambient conditions,
   we
  ask the night astronomer to feel free to adapt the observational strategy 
  (DIT/NDIT) to optimize the observation.
