Example of our weighted pixel averaging. The left plot shows (target with plate-ifu: 8725-9102) the flux of the [OIII]λ5007 emission line. Pixels with S/N < 3 are masked. The black circle indicates the 2 kpc circular diameter aperture where we average the flux for the emission line ratios. The right plot shows a zoom onto the aperture region, showing the percentage of the pixel area captured by the aperture shown in black. We show the value in each pixel that corresponds to the weight of the pixel when we compute the average fluxes.
