10 Jan 2007 | | Abstract: | The SINFONI data reduction pipeline, as part of the ESO-VLT Data Flow System, provides recipes for Paranal Science Operations, and for Data Flow Operations at Garching headquarters. At Paranal, it is used for the quick-look data evaluation. For Data Flow Operations, it fulfills several functions: creating master calibrations; monitoring instrument health and data quality; and reducing science data for delivery to service mode users. The pipeline is available to the science community for reprocessing data with personalised reduction strategies and parameters. The pipeline recipes can be executed either with EsoRex at the command line level or through the Gasgano graphical user interface. The recipes are implemented with the ESO Common Pipeline Library (CPL).
SINFONI is the Spectrograph for INtegral Field Observations in the Near Infrared (1.1-2.45 um) at the ESO-VLT. It consists of the SPIFFI integral field spectrograph and an adaptive optics module which allows diffraction limited and seeing limited observations. The image slicer of SPIFFI chops the SINFONI field of view on the sky in 32 slices which are re-arranged to a pseudo slit. The latter is dispersed by one of the four possible gratings (J, H, K, H+K). The detector thus sees a spatial dimension (along the pseudo-slit) and a spectral dimension.
We describe in this paper the main data reduction procedures of the SINFONI pipeline and the most recent developments after more than a year of SINFONI operations. | | Source: | arXiv, astro-ph/0701297 | | Services: | Forum | Review | PDF | Favorites | |
