Acquisition image from 2010 August 15, where we illustrate the locations of the 1 farcs 0 × 1 farcs 0 extraction windows for the nucleus and stellar population spectra. The square labeled A represents the nuclear extraction window, while squares B and C represent the extranuclear ones, from which we obtained the spectrum of the underlying stellar population.
