Selected point

Select a point to inspect its result.

x-axis
t_1000_ns — t₁₀₀₀ (ns), linear scale, lower is better. Definition
y-axis
score_ler_upper_95_at_5pct_acceptance_v0_1 — LER upper 95% @ 5% acceptance (probability), linear scale, lower is better. Definition
uncertainty
Whisker bars. 0 x-axis and 7 y-axis stored intervals are available in this plotted population. Only complete lower/upper intervals stored under the selected score definition are drawn; Circuit Bench does not infer missing errors.
