General Description

• NoAO observations of a deeply embedded YSO. 
  OBs of the same target to be spread out the whole semester. See time-critical aspects.
  
  The main target is WL4 (aka ISO-oph 128), the brightest star in the FOV. The slit
   angle
  as been chosen such that a second object falls into the slit, which serves as a
   comparison
  object. The separation of both stars is ~16 arcsec. Both targets should be put rather
  symmetrically in the slit. Thus, with 5" nodding, both spectra remain in the spectrographs
  FOV.
  
  SV guiding should be done on the main target (WL4). However, if there is not enough
   flux
  on the slit jaws (0.4" slit!), one of the nearby field stars could be used as well.
  
  The aquisition sequence is setup such that the mid-position between the two stars
   is the 'target'
  coordinate and the SV guide star (-> WL4, SE of the center position) is given
   as offset coordinates
  from the 'target' coordinates.
  
  No telluric standard is needed.

Time-Critical Aspects

• The 9 OBs should be observed spread evenly over the whole semester (best
   visibility April 01 - August 15) 
  with an optimal spacing of ~2 weeks between the individual OBs. Miminum spacing
   between the individual OBs: 
  1 week. Please observe the highest ranked OB (WL4_2329_Mband) first and as early
   in the semester as possible.

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?

• 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
