Example of photometric decomposition for a face-on galaxy (ID = 513105, 455292). The first column shows the face-on mock image generated through the GALAXEV pipeline. The dashed black line represents a circle drawn at the average radius where the pixel value equals 1, distinguishing the background from the stellar halo. The second column presents the two-component GALFIT model (bulge + disk). The third column displays the residuals, where the pixel values are normalized by the maximum value of each galaxy. The fourth column shows the surface brightness profile fitting results.
