This page is dedicated to the SNifs Useful Reduction Package, the data reduction software of the SNIFS instrument. It provides some related links and documents, but does not serve as a source repository.
|Snifs-0-7||26/10/05||flux calibration, cosmic rays, quick_pipeline, wavelength reference tables and calibration.|
|Snifs-0-6||19/07/05||switch to IFU_C_iolibs-6.2, flux calibration, quick scripts (quick_cube, quick_calib, quick_extract, etc.), DISLIN output handler, fit_background, new spatial orientation, corrected exposure time, post-march'05 engineering run masks, documentation.|
|Snifs-0-5||23/11/04||Switch to IFU_C_iolibs-6.1, quick_subsky, center_gauss.|
|Snifs-0-3||31/03/04||This is a bugfix release to comply with gcc 2.9x compilers (create_mask.c)|
|Snifs-0-2||26/03/04||Include 1st-order optimal extraction.|
The SNIFS Reference Manual is automatically generated from the sources via Doxygen. I provide here a recent taggued-release documentation, but the bleeding-edge Snifs-developer Reference Manual can be built directly from the latest sources.
Latest online-version: Snifs-0-7 (26/10/05)
The Euro3D-LCL I/O library is the official Euro3D I/O library, implementing the FITS Euro3D data format according to the latest specifications, and offering a variety of tools for efficient and portable programming (option parsing, session handling, standard and error I/O, etc.). This library, also known as the IFU_C_iolibs library, is heavily used in the SNIFS (and other TIGER-like instruments: OASIS and SAURON) data reduction softwares.
The Euro3D-LCL I/O Reference Manual is directly generated from the 1.0b/6.0b sources via Doxygen.
The SNIFS data reduction software relies on some other libraries:
The data reduction software developped at CRAL for the TIGER-like IFUs was the starting point for the SNIFS data reduction softwares.
Data reduction scheme of OASIS:
I provide here 2nd-generation masks for both spectroscopic channels, as used in the quick_cube script of Acq_scripts. The quality of the optical model is improved with respect to the 1st-generation masks (e.g. no missing/extra lenslets), but they are still not suitable for multi-order optimal extraction.
