A detailed study of this galaxy's centre is important for understanding the innermost structure of the AGN phenomenon.\n  Aims. Our goal is to seek previously undetected structures using additional techniques to reanalyse a data cube obtained with the GMOS-IFU installed on the Gemini North telescope (Schnorr M\\\"uller et al. 2011).\n  Method. We analysed the data cube using techniques of noise reduction, spatial deconvolution, starlight subtraction, PCA tomography, and comparison with HST images.\n  Results.
