Estimated Total Execution Time (hours, including overheads)

• Total execution time: 07:49:38 for an exposure time of 05:40:00

General Description

• H2 1-0 S(1) (2121.3nm) spectroscopy at the head of the Eagle Nebula Pillars
   I and II and the Oph W PDR.
  
  >Pillars I and II: Emission is extended along the pillar edges (see proposal
   figure) with a width
  smaller than a few arseconds 
  The slit will cross the H2 emitting layer at some angle. The nodding throw (15\")
   is large
  enough to allow sky subtraction.
  The final S/N ratio should be >10 per arcsecond along the slit on the brigtest
   sections.
  
  >Oph W: H2 line emission @ 2121.3nm should be extended over the full CRIRES slit.
   Offset position 60" 
  along slit for sky subtraction. 
  The final S/N ratio should be >10 after averaging along the slit.
  
  The goal of the proposal is to get the H2 line profiles and measure the intrinsic
   line widths.
  
  There are three targets in two distinct fields: PillarI-H, OphW-H2 and PillarII_H2.
  Priorities: (1) PillarI-H2 OBs, (2) ophW-H2, (3) PillarII-H2.
  Last OB on PillarII-H2 is shorter than the first two to fit within the allocated
   time.

Special Calibration Information

• Standard wavelength calibration is OK. We just want to measure the 
  intrinsic H2 line width. It is important that we get from the standard
  calibration with the N2O gas cell lines that are not saturated 
  to measure the spectral resolution.
  
  I have not prepared any telluric star observation. I am assuming that
  there is no telluric absorption line overlapping with the H2 line.
  
  Photometric calibration is not required.

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?

• N/A

Do any OBs include wavelength or flatfield calibrations?

• NO

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?

• YES

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
