Abstract

We present the current state of the Data Reduction Software (DRS) being developed at APC, Paris Observatory, Amsterdam University and ESO for the X-shooter echelle spectrograph. X-shooter is the first VLT second generation instrument, which will have its first light during the fall of the current year and will be available to the astronomical community starting April 2009. The DRS will be fully integrated in the ESO VLT data flow environment and it will use the ESO Common Pipeline Library. X-shooter data have two main characteristics, on the one hand the exceptionally wide band (0.3 - 2.4 micron) covered in a single exposure, and on the other hand the spectral format with highly curved orders and tilted lines. After a brief description of the reduction process, the main results obtained up to now on simulated and laboratory data are reported. In particular the precision of wavelength calibration and sky subtraction are discussed.
