VARIABLES
Input Variables (default values):
Parameter | Variable | Value |
---|---|---|
0 | Scale | 1.e-6 |
1 | (-)Power | 4.0 |
2 | Incoherent Background (cm-1) | 0.0 |

with the intensity at q=1 being A, decaying with power -m.
REFERENCE
TEST DATASET
This example dataset is produced by calculating the PowerLaw using 300 data points, qmin = 0.001 Å-1, qmax = 0.7 (Å-1) and the above default parameter values.
