Line model

Parameter	Description	Units	Default value
scale	Scale factor or Volume fraction	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

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