Example spectrum extracted from a spaxel in the central region of the host galaxy of GRB 050709, illustrating the separation of the stellar and gas-phase components. Top: original spectrum containing stellar and ionized gas emission (black) and the model stellar fit (red). Middle: zoom-in of the continuum shown in the top panel. Bottom: spectrum of the gas-phase-only component (blue) together with the error spectrum (black).
