A number of standard settings exists for GIRAFFE. A setting is a unique
The keys INS.SLIT.NAME and INS.EXP.MODE contain the complete setting
information. Alternatively, INS.SLIT.NAME plus INS.GRAT.NAME plus
INS.GRAT.WLEN plus INS.GRAT.ORDER are also unique.
- fibre system (Medusa1/2; IFU1/2; Argus),
- central wavelength (in nm),
- grating order, and
- grating name (HR or LR).
Science data taken in these settings automatically receive a set of daytime
calibrations. Quality Control and trending services are provided for these
The complete table of all GIRAFFE settings is available here: HR,
Most of the settings have a good pipeline extraction and wavelength
calibration. All of them have master calibrations in the archive, except for:
HR379.0 and LR385.8 where the pipeline usually fails in the localization step
A total of 31+8 standard settings are defined per slit unit (fibre system).
With the slit units Medusa1, Medusa2, IFU1, IFU2 and Argus, a total of 195
settings are defined.
