error_factors Second parameter of the lognormal distribution (option 2)

Description

For the lognormal variables, one may specify either the mean $\mu$ and standard deviation $\sigma$ of the actual lognormal distribution, the mean $\mu$ and error factor $\epsilon$ of the actual lognormal distribution.

This corresponds to the mean of the lognormal random variable
