Bool is the final stage of the LHCb detector simulation. Boole applies the detector response to hits previously generated by Gauss. The output is digitized data that mimics the real data coming from the real detector. text/html 2010-04-12T09:19:05+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.physik.uzh.ch/lhcb/start:conddb?rev=1271063945&do=diff CondDB The conditions database stores data describing the state of the LHCb detector at a given time. The CondDB does only include information that varies over time (between runs). Information that usally does not vary is stored in the DDDb.
