GIRAFFE Calibration Files

The GIRAFFE Pipeline release package contains only a minimal set of calibration files. These are the static calibration tables, i.e. line catalogs, grating information, master slit geometry tables, etc. In order to process GIRAFFE observations with the GIRAFFE Pipeline recipes additional calibration files (e.g. fiber localizations, extracted flat fields, dispersion solutions, etc.) are also required.

In order of preference, these calibration files can either be taken from

The last option may be time consuming and is usually not necessary. In almost all cases it is sufficient to use the files from first or the second option, either as they are, or as an initial guess to update them with the calibration recipes of the GIRAFFE Pipeline.

Standard Calibration Data Sets for the GIRAFFE Pipeline

The latest release of the standard calibration data sets is still version 2.8.7. However, these data sets can be used together with the GIRAFFE pipeline version 2.12.2.

The Standard Calibration Data Sets are the calibration files used by the automatic on-line pipeline running at the telescope, and should produce results of comparable accuracy. These calibrations can be used as an initial guess for the calibration recipes of the GIRAFFE Pipeline, in order to create up-to-date calibrations from raw calibration files.

However, if you have calibration files available, which were created by the ESO Quality Control and Data Processing Group for your observations, it is recommended that you start from these calibration files.

The Standard Calibration Data Sets are organized into a set of files to keep the size of the downloads limited. There is one file for each of the 5 GIRAFFE fibre systems and one for the fibre system independent calibrations. These files contain the calibrations for each supported wavelength setup of the high and the low resolution grating.

Calibration data sets for GIRAFFE CCD "Carreras"

These data sets are suitable for GIRAFFE data that has been taken with the new CCD "Carreras", i.e. data which has been observed since May 2008.

Note: Replacing the original GIRAFFE CCD with "Carreras" led to a loss of sensitivity in the blue. The bluest setups for the IFU and Argus slit systems of both gratings (low and high resolution), which were not easy to calibrate even for the old CCD, cannot be calibrated properly at the moment, and are therefore not supported!
