Estimated Total Execution Time (hours, including overheads)
General Description
The goal of this program is to collect CRIRES spectra of RGB stars
found in two globular clusters with different metallicity.
From these spectra, we will derive the 12C/13C ratio at the surface
of these RGB stars in order to better understand the internal mixing
characterising low-mass stars.
All the finding charts are in the I-band since all targets are always very bright
and very easy to find (even in the K band).
They are the brightest and central source in the K-band.
Waiver Requests
Critical Observing Condition Constraints
Time-Critical Aspects
After each science OB, we request that a telluric OB is observed immediately
after
in order to remove the telluric lines.
Each OB of a telluric standard is named with the name of the its corresponding science
OB.
For instance, the OB "Telluric for N6397_65146" has to be executed immediately after
the OB "N6397 AboveBump_65146 K8.8 + AO"

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?
Do any OBs include wavelength or flatfield calibrations?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
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?
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?
