**Specification**

- *Alias:* None

- *Arguments:* REALLIST


**Description**


Shape of the prior distribution for calibrated error multipliers.
Either a single value or number of hyper-parameters values may be
specified.

*Default:* 102.0 (with beta = 103.0) so mean and mode are
approximately 1.0 and standard deviation is about 0.1.
