deerlab.bg_exp¶

bg_exp = <deerlab.model.Model object>¶

Exponential background model

Parameters:

tarray_like: Time vector, in microseconds.
decayscalar: Decay rate

Returns:

Bndarray: Dipolar background vector.

Model

$B(t) = \exp\left(-\kappa \vert t \vert\right)$

Although the bg_exp model has the same functional form as bg_hom3d, it is distinct since its parameter is a decay rate constant and not a spin concentration like for bg_hom3d.
