Example of linear profile fitting for disk scale-length calculation. The top panels show the galaxy face-on (left) and edge-on (right), with white and black lines indicating h_d,SR and the h_d we measured, respectively. The bottom panels display the surface density profile (Σ_*): with vertical lines marking the fitting radius, while the right panel shows the profile within this radius. Our recalculated h_d provides a more accurate measurement of the disk scale-length by better excluding bulge-dominated regions and outer disk noise.
