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