This is explained in more detail in this\npresentation by C. Kleinwort,\n\nhttps://indico.cern.ch/event/337178/session/0/contribution/5/material/slides/0.pdf\n\nNote that the implementation of the averaging constraints is still\napproximate for the time being, but adequate for current purposes\nand superior to the current version of the hierarchy constraints.","Matthias Schroeder",true]],"size":1,"ref":"refs/heads/Alignment-MP-53X-Dev","head":"a281aacedfe8911391735d75285ab4080dfd24fa"}
