Comparison of the elliptical photometry available in the catalogue and the values retrieved with Py2DJPAS for the galaxy 2241-7608, before and after background correction. Blue points represent the values obtained when no background subtraction is applied. Red points represent the values of the photometry obtained applying a background correction. The left panels show the one-to-one relation. The black dashed line shows the one-to-one relation. The middle panels show the difference between our calculations and the SExtractor catalogue values, calculated as Δ MAG=MAG_SExtractor−MAG_Py2DJPAS, as a function of wavelength. The black dashed line shows the 0 target value. The right panels show the S/N image with the aperture used for each calculation. The top row shows the comparison for MAG_AUTO. The bottom row shows the comparison for MAG_PETRO.
