We expand upon our previous analysis of numerical moving-puncture simulations of the Schwarzschild
spacetime. We present a derivation of the family of analytic stationary 1 þ log foliations of the
Schwarzschild solution, and outline a transformation to isotropic coordinates. We discuss in detail the
numerical evolution of standard Schwarzschild puncture data, and the new time-independent 1 þ log data.
Finally, we demonstrate that the moving-puncture method can locate the appropriate stationary geometry
in a robust manner when a numerical code alternates between two forms of 1 þ log slicing during a
simulation.
