NGC 613 is a barred spiral galaxy (Hubble type SBbc) in the Southern Hemisphere. As part of the Carnegie-Irvine Nearby Galaxies Survey (CINGS), we have obtained good-quality B and I band images of this galaxy. We take Fourier transforms along radial cuts in both the B and I band galaxies and compare the phase angles as a function of radius in the two wavebands. The radius at which the B band phase angle and the I band phase angle cross indicates the location of the corotation radius. We compare this with previously determined locations of the corotation radius from sticky particle simulations and from morphological arguments.
