Line model

Parameter Description Units Default value
scale Source intensity None 1
background Source background cm-1 0.001
intercept intercept in linear model cm-1 1
slope slope in linear model Å·cm-1 1

The returned value is scaled to units of cm-1 sr-1, absolute scale.

This model calculates intensity using simple linear function

Definition

The scattering intensity \(I(q)\) is calculated as

\[I(q) = \text{scale} (A + B \cdot q) + \text{background}\]

Note

For 2D plots intensity has different definition than other shape independent models

\[I(q) = \text{scale} (I(qx) \cdot I(qy)) + \text{background}\]
