Simply do pip install wigrad to install this package.
This package calculates the spectral-angular distribution of the number of photons emitted by one electron in a wiggler.
The analytical expressions from the book "The Science and Technology of Undulators and Wigglers" by James A. Clarke are used, pp. 66-67.
Please see demo.ipynb for an example of how to use the module wigrad.py. This example uses the undulator from SLAC (for details see https://arxiv.org/pdf/1912.06737.pdf), the electorn energy is 100 MeV.
