CAR model review questsion

I'm trying to compare the CAR model implementation in pixelpop/models/car.py with the paper. It would be really helpful to have some of the details added into docstrings and how to map variables in the code to expressions in the paper.

• where is \kappa, is it assumed to be 1?
• can you spell out more the connection between the second term in the determinant and the characteristic polynomical, and how this is being calculated... I don't really follow this.
• it looks like phi is \ln R - \mu I, is that correct?
