Abstract: We have selected ground-based ugriz band images of the face-on barred spiral galaxy, NGC 4145, from the EFIGI galaxy survey. We take Fourier transforms along the radial cuts in all wavebands and compare the phase angles as a function of radius between them. The radius at which the phase angles cross indicates the location of the corotation radius. We compare our results with a previously reported corotation radius determined using the potential-density phase-shift method.
