DESCRIPTION
Model describes a Lorentzian (Ornstein-Zernicke) including a flat background.
Resolution smeared version is also provided.
VARIABLES
Input Variables (default values):
| Parameter | Variable | Value |
|---|---|---|
| 0 | Scale | 100.0 |
| 1 | Screening Length (Å) | 50.0 |
| 2 | Incoherent Background (cm-1) | 0.0 |
USAGE NOTES
The function calculated is:
where I0 is the scale factor and corresponds to the scattered intensity at q=0.0.
REFERENCE
TEST DATASET
This example dataset is produced by calculating the Lorentz using 300 data points, qmin = 0.001 Å-1, qmax = 0.7 (Å-1) and the above default parameter values.
