MsdYi

Description

The Yi model for Mean-squared displacement fitting is defined as:

\[\mbox{Height} \cdot \left(1 + \frac{x^4 \sigma}{72}\right) \cdot e^{\left(\frac{-x^2 \cdot MSD}{6}\right)}\]
where:
  • \(MSD\) is the mean squared displacement
  • \(Sigma\) is the standard deviation
  • \(Height\) is the intensity scaling

Properties (fitting parameters)

Name Default Description
Height 1.0 Height
Msd 0.05 Mean square displacement
Sigma 1.0 Sigma
