We acknowledge interesting discussions with D Stauffer and R Ziff. We thank CICyT (AEN97-1708 and AEN97-1693) for partial financial support. The computations have been carried out using the RTNN machines at Universidad de Zaragoza and Universidad Complutense de Madrid.Using Finite-Size Scaling techniques we obtain accurate results for critical quantities of the Ising model and the site percolation, in three dimensions. We pay special attention in parameterizing the corrections-to-scaling, what is necessary to put the systematic errors below the statistical ones.engjournal articlehttp://doi.org/10.1088/0305-4470/32/1/004http://iopscience.iop.org/https://arxiv.org/abs/cond-mat/9805125v2open access5351-73Critical exponentsRenormalization group: Critical-behaviorSeries.Física (Física)Física-Modelos matemáticos22 Física
