General Description

• We aim to measure Sulphur abundance in metal poor stars ([Fe/H]~-2) by
   means of multiplet 3 around 1045 nm. Finding charts have been derived from 2MASS
   J images with the exception of G186-026 for which a DSS2 Infrared image has been
   used, and HD140283 for which 2MASS H image had to be used. Most stars are high proper
   motions stars.
  
  HIP28910telluric: HIP 28910 is a telluric line standard. We need for it ONE SINGLE
   exposure, if possible taken during the same night as one of the science target.
  
  Concerning the recent discovery of possible vignetting problems in detectors #1
   and #4, we confirm that our science is in no way dependent on the spectral coverage
   of these detectors, being the features of interest located in detector #2 (around
   1045 nm in setting 54/0/i).

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• HD 343328 is only observable at the end of the period.

Special Execution Requirements

• Completion of OBs for high priority targets should be preferred with respect
   to partial completion of all the program stars.

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
