General Description

• This run observes 3 different binary brown dwarfs in 3 different imaging
   OBs. In addition there are 3 different OBs for 3 corresponding PSF calibration stars.
   For 2 of our science targets (2MASS 1534-2952, DENIS 1859-3706) and their corresponding
   PSF callibration stars we will use the LGS and observe in H- and Ks-band.

   TTS is the target itself.
  
  The third science target (Kelu 1) is bright enough to be observed with NGS and will
   only be observed in Ks-band (K = 12.35). We know, that the corresponding PSF calibration
   star has a very faint companion, but the distance is fare enough and will not affect
   our sience. Please be also aware of the special time-critical aspects for this target!
   (As described therein)
  
  In all OBs the science object/PSF star should be clearly visible during acquisition
   and should be centered in the array.
  Since we chose the S27 camera, in all OBs the brightest object in the FoV will be
   the science target.
  
  All OBs contain 6 science dither points in each filter. The goal is to stack together
   all images per filter to achieve the necessary S/N for a very good data reduction
   and correction.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Since the contrast and the 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 OBs.
  
  Thank you for your cooperation.

Time-Critical Aspects

• For the target Kelu1 this is a monitoring observation program which will
   be continued in the same period (P81) by ESO-ID 381.C-0527(A).
  Therefore we determined a time interval for this OB (and its corresponding PSF calibration
   star) from April 1st - June 1st. 
  Since we need a minimum epoch difference of 4-6 weeks between 2 observations to
   be able to measure an orbital movement of the binary, we would like to ask you to
   observe this OB as soon as possible in P81. 
  Thank you very much for your cooperation!
