    • i is one of the cosmological parameters. By the Cramer-Rao bound, the inverse of the Fisher matrix gives an estimator of the smallest (co)variance of the parameters. In our previous work, we computed the Fisher matrix exactly, but considerations of the parameter set being used and the experimental data that could be included meant that in this work we compute the Fisher matrix elements numerically.
    • B are exchanged.) From here our estimate of the second derivative is simply the finite difference of the slopes, evaluated at the slightly displaced positions, We tune the step parameters ε to be small enough to achieve numerical convergence of the Fisher matrix.
