Comparison of shape measurements from KSB and GALFIT. Grey scales show the number of points per bin in logarithmic scale. Red lines show y = x. Top: ellipticity components in Cartesian coordinates. Bottom left: position angles, φ, in degrees. The periodicity of φ (of 180 deg) can be seen in the top left and bottom right corners of the plot. Bottom right: galaxy ellipticities.
