Detailed Description

The gaussian lineshape has the form

\[ \mathcal{A}(s) = e^{ -(s-\mu)^2 / 2\sigma^2 }, \]

which is potentially useful for fitting very long-lived contributions that are essentially limited by the experimental resolution, rather than the natural lifetime. This type of parameterisation will assess contributions from interference incorrectly.

Parameter	Interface parameter name	Description
\(\mu\)	lineshapeModifier_mean	Mean of the gaussian distribution.
\(\sigma\)	lineshapeModifier_sigma	Width of the gaussian distribution.
