### Implementation of a method enabling error bar computations for all reconstructed equilibrium quantitites

Participant : Blaise Faugeras.

Error bars on control variables are directly given by the inverse of the Hessian of the minimized cost function. This is not the case for other quantities such as the safety factor profile for example, and the computation of error bars for these important output quantities necessitate the non-trivial computation of their (discrete) derivatives with respect to the control variables as wall as the state variables.
