This operator defines how the stats are printed.

                os << s.name()   << "\t"
                   << s.n()      << "\t"
                   << s.mean()   << "\t"
                   << s.stdDev() << "\t"
                   << s.median() << "\t"
                   << s.eff_sigma(interval) << "\t"
                   << s.eff_sigma(interval03) << "\t"
                   << s.mean(interval.first, interval.second) << "\t"
                   << s.mean(interval03.first, interval03.second) << "\t"
                   << s.eff_sigma(interval) / s.mean(interval.first, interval.second); // << "\t" << s.recursive_effective_mode() ;
