Figure 8.1.0: Integral Field Spectroscopy data reduction principle
pixel accuracy. The final product is thus a 3D data cube where the full spatial information is stored along the
X and Y directions, and the wavelength information is stored along the Z direction. Each plane of the cube is a
monochromatic reconstruction of the SINFONI FOV.
The north south test template traces each of the 32 slitlets by only one fibre exposure; therefore non linearities
of the image scale within the 64 pixel of a single slitlets are currently not corrected and could cause minor slice
to slit ripples in the reconstructed cube.

Required input data
To be able to reduce science data one needs to use raw, product data and pipeline recipes in a given sequence
which provides all the input necessary to each pipeline recipe. We call this sequence a data reduction cascade.
The SINFONI data reduction cascade involves the following input data:
Reference files:
– A reference bad pixel map, indicating known detector defects.
– A list of arc lamp emission lines containing vacuum wavelengths and predicted intensities for wave-
length calibration.
