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).


A CRIRES standalone version of MOLECFIT is currently being developed. Please check the MOLECFIT page for updates.

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.
  • FTS scan of Short Gas Cell (SGC) in the H-band (*.gz, 2.5 MB) and K-band (*.gz, 2 MB)
  • FTS scan of N2O Gas Cell in the LM-bands (*.gz, 1 MB)

High S/N flat fields

On a regular basis, we take flat fields in the YJHKL bands with S/N of ~600 per pixel per exposure. These flat fields can be searched in the CRIRES specific raw data archive by selecting DPR TYPE = FLAT and NDIT = 50.


Will be released in November 2021
