General Description

• Standard long-slit spectroscopy observations of T Tauri stars.
  
  The goal of the project is to detect H2 emission at 2 micron and CO emission at
   4.7 micron.
  
  We use three wave settings (27/1/n, 25/-1/n, 25-1/i) for the three H2 lines searched
   (2.12, 2.22, 2.24 micron)
  and two wave settings (12/-1/i,11/-1/n) for searching the CO lines at 4.7-5.0 micron
   .
  
  We use the technique of nodding along the slit with an ABBA nodding cyle
  
  The observations are performed with AO in the NGS mode for G-1.
  The star it-self is a  AO guide star.
  
  The observations are without AO for G-85 (the star is too faint in the R-band)
  
  We use a 0.4" slit, and we employ the AutoNodOnSlit template.
  
  The observations are performed with the slit in the North South direction.
  
  The observations of each star are splitted in several OB's in general
  one for each order observed.
  For example, the OB G-85_CO_order11 correspond to the observations 
  of CO for G-85 with the order 11/-1/n.
  This is done for avoiding OB's with duration longer than 1h.
  
  Observations of telluric standards are required inmmediatelly preceding/following
   the
  science observations. OB's for these observations are included as well.
  They are named as CAL_ where  is the name of the OB
   to whom the calibration 
  belongs
  
  We strongly suggest to perform the observations of the H2 OB's of a same star during
   the same night.
  We strongly suggest to perform the observations of the CO OB's of a same star during
   the same night.
  
  Lamp calibration observation is performed for the wave-ID's 27/1/n and 12/-1/i,
   11/-1/n. 
  The wave-ID's 25/-1n and 25/-1/i will be calibrated with telluric emission lines.
  
  
  NOTES:
  *A waiver for changing from the wave-ID 12/1/n to the wave-ID 12/-1/i was accepted

Waiver Requests

• A waiver was accepted for changing the wave-ID 12/1/n for the wave-ID
   12/-1/i

Critical Observing Condition Constraints

• No critical observing conditions.
  However, since the targets are relatively faint, observations at low airmass are
   preferred.

Time-Critical Aspects

• Observations of this run (B) should be performed in the months of june
   and july.
  The velocity shift of the targets is necessary for the detection of the CO lines
   at 4.7 micron

Special Execution Requirements

ToO Activators List

Do the README file and the instrument comments of the telluric stars
 OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral
 type and allowed spectral range?

• YES

Do any OBs include wavelength or flatfield calibrations?

• YES

If you are observing Moving Targets, have you attached suitable ephemeris
 files to your OBs?

• N/A

If the slit viewer guide star is different from the target, are the RA
 and DEC offsets accurate to within 0.05 arcsec and do they take into account the
 relative proper motion between the two objects?

• N/A

If you have preferences which OBs should be executed first for objects
 at similar RA, did you make use of the User Priority field in the OBs?

• YES
