Averaged data cubes obtained of the PZ Tel companion in H band (upper row) and K band (lower row) at position angle − 30°. From left to right in each row: cube after data reduction, eastern part of cube after two-dimensional polynomial fit of the primary PSF and removal of the primary halo, cube after subtracting the radial symmetric part of the primary PSF, and cube after subtracting the radial symmetric part of the primary PSF and additional spectral deconvolution. For clarity, flux is inverted in the last three images in each row. See text for details.
