Preregistered H2 lane

H2 Visibility Explorer

Static calculator for the anchor observable V/V0 = exp(-ΓTΔx²). Adjust Γ, T, Δx, and δtot; the page updates the live visibility and the corresponding Γfloor.

Illustrative calculator only. This page mirrors the preregistered H2 observable and floor construction; it is not a discovery claim, lab noise model, or instrument calibration.

Current V/V0 at the selected Γ, T, and Δx.
Computed Γ floor

Selected Γ relative to the computed Γfloor.
At reference floor The selected Γ sits close to the computed floor for the current T, Δx, and δtot.
Near floor
The floor line is computed from the current nuisance budget and geometry. The selected Γ is shown separately so you can compare it directly against the floor.

Reference point

Defaults reproduce the anchor reference posture: T = 10⁻⁶ s, Δx = 10⁻³ m, δtot ≈ 1.15 × 10⁻³, giving Γfloor ≈ 1.15 × 10⁹ s⁻¹ m⁻².

Readout discipline

Stable nulls bound the allowed deformation. Positive excess would be escalation under the preregistered protocol, not a page-level discovery claim.

Companion surfaces

The canonical gallery ranks this calculator as simulation #1. The Closure Explorer remains separate because it is a specification map, not a simulation.
