General Description

• We want to map the line emission from the DG Tau small scale jet. We will
   use SINFONI
  in AO with the H and K spectral gratings and the 100 mas x 50 mas spatial sampling.
  
  DG Tau is the brightest near-IR source in the SINFONI field: H=7.9 and K=6.8
  
    The continuum source DG Tau is bright (R=11.4) and unresolved and will therefore
   be used as NGS for the AO. We want to center the SINFONI field on DG Tau and rotate
   the SINFONI field of view by 46 degree in order to align the CCD columns with the
   (one-sided) blueshifted jet emanating from the continuum source at PA = 226 degrees.
   
  
    DG Tau is bright in the near-IR: H=7.9, K=6.8. We plan to use the continuum emission
   from DG Tau to estimate the PSF.  We will therefore use short exposures with small
   DITs (8s in the H band and 2s in the K band) in order to ensure to stay in the linearity
   regime on the continuum for seeing conditions > 0.6". We will get longer exposures
   on the jet (with DITs of 15s in the H band and 5s in the K band). The DIT used for
   the longer exposures ensure that we stay below saturation for seeing conditions
   > 0.6".

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Seeing < 0.8"
  Airmass < 1.7. The object is observable at airmass < 1.7 for typically 3 hours
   per night over the semester.
  Moon distance > 30 degrees.

Time-Critical Aspects

• Avoid following periods where the bright moon (IL > 0.7) is within
   30 degrees of target:
  from 17-oct-2005 to 21-oct-2005
  from 14-nov-2005 to 18-nov-2005
  from 12-dec-2005 to 16-dec-2005
  from 08-jan-2006 to 12-jan-2006

Special Execution Requirements

• DG Tau is the brightest IR source in a 1'x1' field (H=7.9, K=6.8).
  
  The SINFONI field should be rotated at PA=46 degrees and centered on DG Tau A.

Special Calibration Information

• One reference star that could be used for telluric line removal is HD290798
   (A2V).
