property CalibrationMaterial.lowE_gaussian_pdf

Low energy CT attenuation Gaussian probability density function (PDF).

A tuple \((\mu, \sigma)\) with the mean and standard deviation values for a Gaussian (normal) probability density function model for low energy attenuation values:

\[y(x) = \frac{1}{\sqrt{2\pi\sigma^2}}e^{-\frac{1}{2}\left(\frac{x-\mu}{\sigma}\right)^2}.\]

When set, gets precedence over the lowE_pdf attribute.

Examples

To get the current lowE Gaussian PDF:

>>> mean, std = calibration_material.lowE_gaussian_pdf

To set a new lowE Gaussian PDF:

>>> calibration_material.lowE_gaussian_pdf = (new_mean, new_std)

To unset the lowE Gaussian PDF model:

>>> calibration_material.lowE_pdf = None
