SAURON (Spectrographic Areal Unit for Research on Optical Nebulae) is a panoramic integral-field spectrograph using a lenslet array based on the TIGER principle (Bacon et al. 1995; see also the OASIS webpage). It is a dedicated instrument, mounted on the William Herschel Telescope (WHT) on La Palma. SAURON has a large field-of-view, high throughput, and allows simultaneous sky subtraction. Its design is optimized for studies of the stellar kinematics, gas kinematics, and line-strength distributions of nearby spheroids (de Zeeuw et al. 2002). Associated with it is an extensive data reduction and analysis software, XSauron, which was developed at CRAL to obtain fully calibrated spectra and the associated kinematic and line-strength measurements (Bacon et al. 2001).
