The Kraken-like merger ($z=1.6$, $M_{\\rm Tot} = 8\\times10^{10}\\,$M$_{\\odot}$) is gas-rich, deposits most of its mass in the inner $10\\,$kpc, and is largely isotropic. The Sausage-like merger ($z=1.14$, $M_{\\rm Tot} = 1\\times10^{11}\\,$M$_{\\odot}$) leaves a more extended mass distribution at higher energies, and has a radially anisotropic distribution.
