Common implementations of peaks, backgrounds for other models.
Functions
|
An affine/linear background. |
|
Lorentzian plus affine background multiplied into fermi edge with overall offset. |
|
Fermi edge, with somewhat arbitrary normalization. |
|
Fermi step edge with a linear background above the Fermi level. |
|
TODO, unify this with the standard Gaussian definition because it’s gross. |
|
Some constants are absorbed here into the amplitude factor. |
|
Fermi function convolved with a Gaussian. |
|
Fermi function convolved with a Gaussian. |
|
Fermi function convoled with a Gaussian together with affine background. |
|
A straightforward Lorentzian. |
|
A double lorentzian model. |
