Example of a pyPipe3D fit to the central spectrum (5″ diameter) of CAVITY49137 extracted from the IFS datacube. In the top panel, the black line represents the original spectrum, along with the best fitted stellar population (SSP model, cyan). The pure emission line spectrum after subtracting the best stellar population model is shown as a solid yellow line (SSP residual). The inset is focused on the Hβ-[OIII] spectral region to highlight the quality of the fit. The vertical shaded regions indicate the wavelength ranges masked during the fitting process. The bottom panels show some examples of emission line fittings (emission line (EL) model, red line).
