General Description

• These observations are dedicated to the spectroscopic characterization
   of planetary mass objects as companions of young stars or free-floating objects
   in young, nearby associations.
  
  The four companions GSC8047B, ABPicB, TWA5B and DHTauB are observed using the NGS
   mode of SINFONI. the four isolated objects OTS44, CHa110913, KPNO Tau4 and the wide
   companion (90") Glise417B are observed in noAO mode. The two grisms J and
  H+K are used, associated with the 25mas camera in NGS mode and the 250mas camera
   in noAO mode. A simple auto jitter or a sequence of generic offsets are used for
   these observations.
  
  IOVirginis and 2MASS0345 are two reference objects observed also in J and H+K. Special
   care must be taken for the observation of the bright giant IO Virginis, using the
   NGS fast mode to avoid any saturation of the detector.
  
  No special calibrations are required for these observations. In case of problmes,
   please contact: Christophe Dumas (cdumas@eso.org), Gael Chauvin (gael.chauvin@obs.ujf-grenoble.fr),
   or Patricio Rojo (pato@das.uchile.cl)

Waiver Requests

• 80.C-0590A.01.WAV accepted
  
  - What technical requirement we wish to override:
  The IO Virginis star is a bright (J=6.6, H=4.8, K=3.6 and R=16) giant that we wish
   to observe with SINFONI using the NGS_fast aquisition mode to avoid any problem
   of saturation with the J and H+K grisms and the 25mas platescale. According to the
   SINFONI ETC (version 3.2.1), if we use the small 25mas platescale with DIT = 60.0s
   in J and 1.0s in H+K, the maximum flux stays below 10% of the detector linearity.
   Therefore, this service mode observation will not create any remnants on the SINFONI
   detector.
