There are few direct measurements of ICM velocity structure, despite itsimportance for understanding clusters. We present a detailed analysis of thevelocity structure of the Centaurus cluster using XMM-Newton observations.Using a new EPIC-pn energy scale calibration, which uses the Cu Ka instrumentalline as reference, we are able to obtain velocity measurements withuncertainties down to $\Delta v \sim 79$ km/s. We create 2D spectral maps forthe velocity, metallicity, temperature, density, entropy and pressure with anspatial resolution of 0.25'. We have found that the velocity structure of theICM is similar to the velocity structure of the main galaxies while the coldfronts are likely moving in a plane perpendicular to our line of sight with lowvelocity. Finally, we have found a contribution from the kinetic component of<25\% to the total energetic budget for radius $>30$ kpc.
