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)=scale(A+Bq)+background

Note

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

I(q)=scale(I(qx)I(qy))+background
