Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

// Curvature returns κ = r/(r² + (p·h/2π)²)
func (G16Helix) Curvature() float64 {
	phTerm := Pitch * RisePerBP / (2.0 * math.Pi)
	return HelixRadius / (HelixRadius*HelixRadius + phTerm*phTerm)
}

// Torsion returns τ = (p·h/2π)/(r² + (p·h/2π)²)
func (G16Helix) Torsion() float64 {
	phTerm := Pitch * RisePerBP / (2.0 * math.Pi)
	return phTerm / (HelixRadius*HelixRadius + phTerm*phTerm)
}

// StabilityMetric returns exp(-Σ|τ(n)|·φ⁻ⁿ)
func (G16Helix) StabilityMetric(torsions []float64) float64 {
	sum := 0.0
	phiPower := 1.0
	for _, t := range torsions {

Torsion returns τ = (p·h/2π)/(r² + (p·h/2π)²)
