General Description

• The aim of this program is to obtain CRIRES high resolution spectra of
   
  H2 1-0S(1) emission at 2.12 micron  with the wave-ID 27/1/n (2117.7 nm)
  H2 1-0S(0) emission at 2.22 micron  with the wave-ID 25/-1/n (2236.1 nm)
  H2 2-1S(1) emission at 2.24 micron  with the wave-ID 25/-1/i (2242.8 nm)
  and the CO ro-vibrational lines at the 4.7 microns employing two waveIDs:
  (12/1/n and 11/-1/n),
  of the T Tauri star V1647 Ori. 
  
  This star is at the beginning of new outburst period.
  
  
  The observations 
  (i) are WITHOUT AO.
  (ii) employ a NS slit of 4", 
  (iii) use chopping and nodding in the slit.
  
  The observations start by acquisition, thereafter each wavelength ID is observed.
  In total we observe five wave ID settings. Before each waveID setting a wavelenght
   
  calibration observation is requested (except for settings at 4761.0 and 5034.8 nm
   
  because there is no suitable lamp).
  
  V1647 Ori has K mag =7-10 (it is a variable star) the expect S/N/pixel is 200-20
  
  V1647 Ori is the brightest IR source in the 30" vicinity of the given 2mass coordinates.
  There is a nebulae north of the object (see attached image).
  
  The observation of a spectrophotometric standard star (HIP 26594) is required immediately
   preceding or 
  following the science observations. We provide the OB STD_V1647Ori_CRIRES_epochXX
   for this.
  HIP 26594 has K=4.8 we expect a S/N/pixel of  300 @ 2121.8 nm
  
  IMPORTANT: scheduling (!)
  
  Monitoring observations:
  The run consist of four (4) observations spaced 1.5+-0.5 months:
  The first one should be executed as soon as possible (October) (note NOV 19: partially
   executed in the 21/22 oct night)
  The second should be executed in November-December   (note NOV 19: executed in the
   17/18 Nov night)
  The third  should be executed in January-February 
  The fourth should be executed in February-Mars 
  
  Quasimultaneous FORS2 observations (within few days after CRIRES observations) should
   be executed (proposal run C)
  
  NOTE (added 19 NOV): in the proposal observations in 3 epochs were requested,
  but, data from october (epoch 1) was incomplete (telluric standard observation was
   not completed).
  For this reason a fourth epoch (observation on February-Mars) was added to the program.

Waiver Requests

• Two waivers have been approved.
  
  1. For OB's of duration larger than 1h
  2. For including the additional observation with the wave-ID 25/-1/i (ref=2242.8
   nm). 
     We aim to cover the H2 line at 2.24 micron with chip 3

Critical Observing Condition Constraints

  Quasimultaneous FORS2 observations (within few days after CRIRES observations) should
   be 
  executed (proposal run C)

   preceding or following the science observations.
  We provide the OB CAL_V1647Ori_CRIRES_epochXX  for this.

ToO Activators List

• ---(Empty)---

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?

• YES

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
