change to fit for \xi not \beta #8

Closed davidwhogg closed 7 years ago

davidwhogg commented 7 years ago

Let's define

\xi \equiv \ln \sqrt{ \frac{v+c}{v-c} }

and fit for \xi not \beta. With this definition (or maybe with the + and - reversed),

x' = x - \xi

have just changed this in the paper, will code it now.
