General Description

• Programme 383.D-0153: The atmosphere of red supergiant stars probed with
   CRIRES 
  PI: Eric JOSSELIN (josselin@graal.univ-montp2.fr)
  5 hours allocated on CRIRES, priority B. 
  
  As this programme includes the study of water lines in stellar atmospheres, we ask
   for photometric nights, 
  and observations of calibration stars (spectral type B) just before or after the
   science targets. OBs have been 
  filled for these calibrators. They are : 
  HIP 79153 (science: HD 143183)
  HIP 87220 (science: HD 160371)
  HIP 88012 (science: KW Sgr) 
  HIP 88298 (science: VX Sgr) 
  HIP 95073 (science: HD 181475)

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Photometric nights are requested, to ensure a proper substraction of telluric
   lines, 
  as this programme includes the study of water lines in stellar atmospheres.

Time-Critical Aspects

• None.

Special Execution Requirements

• We need observation of calibration stars (spectral type B) just before
   or after the science targets.

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?

• N/A
