General Description

• The goal of this proposal is to derive the fluorine abundance (from the
   HF @ 2.335 microns line) in galactic and extragalactic carbon stars. Please observe
   one telluric star  after each scientific target star (the OB name of the telluric
   refers to the corresponding scientific target)
  We need a SNR>>100 for the science and telluric stars. Due to the brightness
   of the telluric stars, finding charts for them are useless.
  A waiver was aproved concerning this point (see waiver requests). For science stars,
   finding charts are K-band are provided. Any way, the target stars are always the
   central (brigthest) object in the K-band view. There is no ambiguity. 
  
  Please, in the following, send also a copy of any correspondence to the collaborator
   P. de Laverny, laverny@oca.eu.
  Thank you

Waiver Requests

• Dear Carlos,
  I am pleased to inform you that your waiver request to not include
  the finding charts for telluric in your programme 080.D-0310(A) was granted.
  Be aware that in case a target appears double or ambiguous, the night
  astronomer will either pick one source according to his best judgment,
  or cancel the OB.
  With best regards,
  Michael Hilker

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• None

Special Execution Requirements

• ---(Empty)---

Special Calibration Information

• We request the observation of one telluric star (we provide the OBs) after
   each scientific target

ToO Information

• ---(Empty)---

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?

• 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
