General Description

• This is a spectroscopic run for only one target (binary brown dwarf) with
   the 0.3" longslit. The binary system has unresolved magnitudes of R=19.2 and I=16.8
   and the two components are separated by ~0.38". To be able to resolve the individual
   spectra we will need superb seeing conditions (<=0.4"). 
  To achieve the required dispersion we use the non-standard 100kHz,1x1,high read-out
   mode together with the high-resolution collimator COLL_HR+7.
  
   
  Acquisition:
  ------------
  To fit both Kelu-1 components in the slit, the rotator on sky has to be -42.9 degrees!
   It is very important, and thus PLEASE make sure, that both! binary components stay
   in the slit during the whole observation!!!!! 
  
  We provide 3 Finding Charts (including a 2'x2' and a magnified one) for the science
   OBs with all relevant coordinates and the rotator (=slit) orientation. 
  
  
  OBSERVATION:
  ------------
  This run consists of two different spectroscopic science OBs for which we use the
   1200R+93 grism with the GG435+81 filter and the 1028z+29 grism with the OG590+32
   filter, respectively.
  For the corresponding telluric standard OBs we chose HD121847 with spectral type
   B8V and R=5.24.
  
  Since we use the non-standard read-out mode, please execute the necessary daytime
   callibrations after each of the science OBs!!! 
  PLEASE be also aware about  the special calibration information for this run!!!
   (As described therein)
  
  THANK you very much for your support concerning all the different issues of this
   run!!!!

Critical Observing Condition Constraints

Special Calibration Information

• We added two calibration OBs corresponding to the science OBs:
  CAL_telluric_standard R_spec and CAL_telluric_standard z_spec, respectively, to
   be able to perform telluric correction during data reduction. We chose the standart
   HD121847 (B8V) with R=5.24. 
  Please execute these OBs right after their corresponding science OB. Please be aware
   that the slit orientation has to be the same as for the science OB (as indicated
   in the OB). 
  If possible, please place the telluric standart at the same position on the science
   detector as Kelu1 (=science target) in the OB before. This will ease any necessary
   correction of the science data.
  If it turns out to be necessary to change the telluric standard, a range between
   B4-A0 will be acceptable. Nevertheless it is very important!!!! to observe at nearly
   the same airmass as the science object.
  
  Since we use a non-standard intrument setup with the COLL_HR+7 and the 100kHz,1x1,high
   read-out mode, please perform daytime calibrations for domeflats and arcs in this
   special mode and the corresponding grism, the morning after each of the science
   OBs has been observed!!! 
  Thank you for your cooperation!
