Description¶
This is a fitting function that makes use of the complementary error function for detector-tube calibration
The function \(f(x)=A \cdot erfc(\frac{B-x}{C}) + D\) with the following constraints:
- \(D \geq 0\) 
- \(f(x) = -2A\) if \(A<0\) 
Properties (fitting parameters)¶
| Name | Default | Description | 
|---|---|---|
| A | 2000.0 | Half value at minus infinity minus half value at plus infinity | 
| B | 50.0 | Mid x value | 
| C | 6.0 | Width parameter | 
| D | 0.0 | Minimum value - must not be negative |
