CRIRES-Specific Tools and Tips

This page refers to the upgraded CRIRES which is currently installed at UT3. For the original (pre-upgrade, pre-August 2014) CRIRES please use the following link.
 

Catalogues of telluric standard stars:

Catalogues of spectro-photometric standard stars:

Optical Spectrophotometric Standards of SpT B4-A9. Models for these stars in the range 950 to 5300 nm are collected in this gzipped FITS binary file, part of the static calibration frames (19.3 MB).

Line lists

  • Calibration tables from NIST. This link provides wave numbers for a number of molecules, useful to calibrate CRIRES spectra either from atmospheric lines. In wave number, CRIRES spectral range is [1850 - 10520]/cm.
  • The wavelength calibration of CRIRES below 2500 nm is based on a UNe hollow cathode lamp.  

CRIRES pipeline

Will be released in August 2021

Differential tracking - not offered in P108

Differential tracking allows to close the loop and/or to guide on an object that is moving relative to the target to be observed. Typical examples of the use of such a mode are:

  • using a satellite of a planet as an AO guide star to observe a feature on the parent planet;
  • using a (angularly small) planet, asteroid or comet to observe a feature moving relative to its optical photo-center;
  • using a star as an AO guide star or SVGS to observe a planet, asteroid, comet passing in its vicinity.

Differential tracking is offered in service or visitor mode. However, some complicated programmes (for example observations of Jupiter whilst using one of its Moons to close the loop) are best performed in visitor mode. See Section 19 of the User Manual for details regarding this mode.
