a, Radial velocity; b, dispersion; c, the skewness h3; d, kurtosis h4. Black contours show the K-band continuum at intervals of 1 mag arcsec−2. The median 1σ errors are 5.8 km s−1 for the velocities, 6.8 km s−1 for dispersion, 0.06 for h3 and 0.07 for h4. The skewness clearly shows the commonly seen anti-correlation with the velocity49.
