Comparison of different data reduction pipelines for the SPHERE/IFS data. Top: SPHERE/IFS dispersion solutions of the reduced 3D data cubes resulting from the standard ESO pipeline EsoRex, the Data Reduction, and Handling (DRH) of the SPHERE consortium, and the vlt-sphere Python package tracing the separations of satellite spots. Bottom: Satellite spots showing strong spectral gradients in the count rates at the edges of telluric absorption bands.
