The documentation of the lognormal_distribution constructor indicates that the second and third arguments are the mean and standard deviation parameters (the desired mean and standard deviation of the log of the generated variables). Actually, the second and third arguments of the constructor are the mean and standard deviation of the lognormal distribution (the desired mean and standard deviation of the generated variables). The documentation for the function call operator refers to a mean and sigma that should differ from the mean and sigma referred to in the constructor.
