The columns show: position respect
to the brightest cluster galaxy (X,Y), ellipticity of the mass
distribution ($\epsilon$, expressed as $a^2-b^2/a^2+b^2$, were $a$ and
$b$ are the semi-major and semi minor axes of the ellipse that
describes the light distribution of the clump), position angle
($\theta$), velocity dispersion ($\sigma_0$), core radius ($r_{\rm
core}$) and scale radius ($r_{\rm cut}$). Values into brackets are not
optimized. The coordinates of the brightest cluster galaxy are $\rm
RA=4^{h} 54^{m} 10.87^{s}$, $\rm DEC=-3^{\circ} 0\arcmin
54.00\arcsec$.
