MuH

Description

Fitting function for use by Muon scientists defined by:

A(t)=A0(t)6eλte(σt)22(1+cos(ωDt+ϕ)+2cos(ωD2t+ϕ)+2cos(3ωD2t+ϕ))

A0 is the amplitude,

λ is the exponential decay rate,

σ is the gaussian decay rate,

ωD=2πνD where νD (MHz) is the oscillating frequency,

and ϕ (rad) is the phase at time t=0.
