General Description

• The aim of this programme is to study a wide binary system. LOri167, in
   the Lambda Orionis young cluster through imaging and spectroscopy observations.
   
  
  We have submitted three OBs, one for imaging and two for spectroscopy:   (i) OB
   LOri167_ima: imaging of the young binary in JHKs  (ii) OBs LOri167_spec1 and LOri167_spec2:
   OBs to obtain spectra of the binary in the H-band. Since we need to integrate ~3.5h
   hours on-source,  we have submitted two similar OBs of 1:40h each.  
  
  IMAGING:
  The FOV has been centered to avoid any star brighther than 11 mag. Therefore, the
   target (LOri167) is not at the center of the ISAAC imaging field of view or the
   spectroscopic acquisition image. The brightest object in the field of view has K=12.00,
   H=12.2 and J=12.9 mags. 
  We have included a jitter box width of 16" that will never place a very bright star
   (K=9.14mag) NE from LOri 167  (see finding chart) within the FOV.
  
  SPECTROSCOPY:
  For the spectroscopic acquisition we will use the NB_2.09 filter to avoid the saturation
   
  of the detector by the brightest star in the field (with Ks=9.14 mag). 
  We have checked that this star does not saturate the detector in a DIT=20secs exposure.
  The primary star of the binary system should be detected in the NB_2.09 acquisition
   image, due to the magnitude of the primary (Ks=16.62 mag).
  In addition, in order to have both stars withing the slit, we have included a rotation
   angle of PA=91.7 deg (using the convention from North to East, see the finding chart)
   in the acquisition.
  Although the acquisition is done the NB_2.09 (because the primary is bright enough
   to be detected in 60 secs.) the science spectra will be taken in the H-band (1.65mic).
  
  For the calibration (telluric standard) we would prefer a featureless A0 star.
  
  Thank you very much.
