Two different bond criteria, the configurational and self-bound ones, defining a cluster have been used. In addition to the percolation threshold occupation probability and the percolation threshold fluid density, the correlation length exponent and the wrapping probability at the percolation threshold, have also been evaluated. It is found that parameters and exhibit not only strong temperature dependence but also, unlike the case of lattice systems, dependence on the nature of the system considered and the employed definition of the cluster.
