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.

Generic Tools and information

• Exposure Time Calculator (CRIRES ETC)
• Phase 1 Proposal Preparation and Submission
• Phase 2 Proposal Preparation for Service Mode observations
• Phase 2 p2
• Moving targets - ESO compliant ephemerides files generator
• CRIRES specific raw data archive
• NICMOS Units Converter

High S/N flat fields

On a regular basis, we take high S/N flat fields in all wavelength settings, with a minimum S/N of 500 per pixel per exposure. The flat fields are available in the CRIRES specific raw data archive and can be searched there by selecting DPR TYPE = 'FLAT', NDIT '>15' and the desired wavelength setting.

Data Reduction Pipeline

Upgraded instrument: all information is provided on the cr2res pipeline page. Note that the cr2res pipeline is NOT compatible with data taken with the original instrument (pre-upgrade).

VIPER: RV analysis tool  

The RV analysis tool VIPER allows the calculation of radial velocities from CRIRES data with a simultaneous wavelength reference (gas cell data or telluric lines). In case of bugs, questions or requests for feature options, send email to viper@uni-goettingen.de starting the subject with VIPER. Publications using VIPER should cite the following article Zechmeister, Köhler and Chamarthi 2021, Astrophysics Source Code Library, record ascl:2108.006.

Molecfit: correction of telluric lines

A prototype Molecfit workflow for CRIRES has been released.

Line lists and FTS scans of gas cells

• Calibration tables from NIST. This link provides wave numbers for a number of molecules, useful to calibrate CRIRES spectra 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)
  

Catalogues of telluric standard stars:

• Hipparcos A1 stars or earlier, suitable for J, H, K, and L bands spectroscopy
• Hipparcos B8 or earlier with V <4.0 or B8 to G0 with V < 4.8, suitable for M-band spectroscopy
  
• Hipparcos O type stars (from ISAAC)
• Hipparcos B type stars (from ISAAC)
• Hipparcos G type stars (from ISAAC)

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).
