estimator.alphaf

estimator.alphaf(sigma, q, sigma_is_stddev=False)[source]

Gaussian width σ, modulus q → noise rate α

Parameters:
  • sigma – Gaussian width parameter (or standard deviation if sigma_is_stddev is set)
  • q – modulus 0 < q
  • sigma_is_stddev – if set then sigma is interpreted as the standard deviation
Returns:

α = σ/q or σ·sqrt(2π)/q depending on sigma_is_stddev
