\subsection{Spinning BH\pages{2 Peter}} +As a first example we perform simulations of a single distorted rotating black +hole. We use \codename{TwoPunctures} to set up initial data for a single +puncture of mass $M_{\mathrm{bh}}=1$ and dimensionless spin parameter +$a = S_{\mathrm{bh}}/M_{\mathrm{bh}}^2 = 0.7$. Evolution of the data is +performed by \codename{McLachlan}, apparent horizon finding by +\codename{AHFinderDirect}, gravitational wave extraction by +\codename{WeylScal4} and \codename{Multipole}. Additional analysis of the +horizons is done by \codename{IsolatedHorizon}. The runs where performed +using fixed mesh refinement provided by \codename{Carpet} using 8 levels +of refinement on a quadrant grid (symmetries provided by +\codename{ReflectionSymmetry} and \codename{RotatingSymmetry180}). The outer +boundaries where placed at $R=256M$. We performed runs at 3 different +resolutions. The low resolution was $0.024M (3.072M)$, medium was +$0.016M (2.048M)$ and high was $0.012M (1.536M)$ where the first number is the +resolution on the finest grid and the second number in parenthesis is the +resolution on the coarsest grid. The runs where performed using the tapering +evolution scheme in \codename{Carpet} in order to avoid interpolation in +time during prolongation.
