In recent years many groups have used Fisher, Fisher, and Huse (FFH)dynamical scaling to investigate and demonstrate details of the superconductingphase transition. Some attention has been focused on two dimensions where thephase transition is of the Kosterlitz-Thouless-Berezinskii (KTB) type. Piersonet al. used FFH dynamical scaling almost exclusively to suggest that thedynamics of the two-dimensional superconducting phase transition may be otherthan KTB-like. In this work we investigate the ability of scaling behavior byitself to yield useful information on the nature of the transition. We simulatecurrent-voltage (IV) curves for two-dimensional Josephson junction arrays withand without finite-size-induced resistive tails. We find that, for thefinite-size effect data, the values of the scaling parameters, specifically thetransition temperature and the dynamical scaling exponent z, depend criticallyon the magnitude of the contribution that the resistive tails make to the IVcurves. In effect, the values of the scaling parameters depend on the noisefloor of the measuring system.
