Stellar continuum fitting in the blue and red spectra of NGC 1365, one of the galaxies targeted by the S7 survey. The flux calibrated raw spectrum (blue curve) and the stellar continuum fit to the spectrum using pPXF (red curve) are shown. Left panel: integrated blue spectrum extracted from the entire S7 FOV and zoomed in the region around Hβ and [O III]λ4959,5007 emission lines. Right panel: spectra in the red cube zoomed in the region around [N II]λ6549,6585, Hα, and the [S II] doublet. The x-axis in both the panels shows the observed wavelength.
