Top panel: continuum MUSE image of NGC 2906. The continuum image was obtained as the mean of the median values in two wavelength ranges: 5620–5750 Å and 6890–7000 Å. Left panel: nuclear peak shown by a cross symbol and the position of the supernova SN2005ip represented by the star symbol. A zoom of the region selected by the white box is shown on the right. Right panel: region showing the distribution of the spectra (white dots) which have been chosen for the analysis. Each spectrum is identified by a letter (a, b, ..., k, l) in order to allow the reader to easily find its position. Bottom panel: Hα peak emission of the same regions as described in the top figure.
