2.1.1. istdev
1for standard deviation of batches2for standard deviation of every histroies
The formula is as follows: \[ \sigma = \sqrt{ \frac{\sum_{i=1}^N(x_i w_i / \bar{w})^2 - N \bar{X}^2}{N-1}} \]
2.2. Tally
factormultiply the output (Qty / primary particle) by this- this is set to match the actual number flux.
