Flux density in the form of the real part of the visibility, as a function of uv distances along the minor axis. Each data point represents the mean value per 100 kλ bin. The galaxies that were fit in a circular exponential disk model are marked in an asterisk. The uncertainties represent the standard deviation. Both the data (circle) and the residual (diamond) visibilities are shown. The residuals are created by subtracting the best-fit model (solid black line) from the data.
