Top panels: reconstructed images derived from a VIMOS-IFU data cube showing the central of the early-type galaxy NGC 3923. Top left: an example of the image derived from the original data cube as produced by the pipeline. Top right: image derived from the corrected cube. Bottom left: numbering scheme of the four VIMOS-IFU quadrants. Bottom right: for comparison, we show an ACS/WFC F606W image of NGC 3923, binned up to the spatial sampling, field-of-view and broadened to ~ seeing of the VIMOS data-cube. For the three images of NGC 3923, the orientation is north to the right and east to the top.
