Reconstructed PSF from the spatially unresolved BLR emission. Left: PSFs measured from the drizzle cube for the Hα and Hβ BLR emission, respectively, as described in Sect. 5.3. The reconstructed Hβ PSF is less extended than Hα, being at shorter wavelengths and therefore associated with a smaller FWHM. Right: visualisation of the BLR subtraction in an individual spaxel at 0.14″ north-east of the nucleus, using the Hβ (bottom) and Hα (top) BLR template. The blue spectrum is the original continuum-subtracted spectrum in the spaxel. The orange line is the BLR model. Using the broad spectral windows marked in grey, the BLR model is scaled to fit the original spectrum. The black curve shows the residual to that fit, which is the BLR-subtracted spectrum.
