2.1.1. istdev

  • 1 for standard deviation of batches
  • 2 for 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

  • factor multiply the output (Qty / primary particle) by this
    • this is set to match the actual number flux.
