+ | EVGEN records (truth level). The format uses Google protocol buffers. | ||
+ | It uses varints for integer values (and, by design, for 4-momenta and vertex). | ||
+ | It's efficient format for events with large number of particles. | ||
+ | The file sizes for EVGEN files are typically 30% smaller than for traditional ROOT files (with fixed bytes for floats and integers). | ||
