[ALPS-users] what is the prefactor of stiffness?

Dear all, I am now studying the 3D bose glass model. By using SSE, I got the stiffness is 2.2427 from the following setting: LATTICE_LIBRARY="lattices.xml"; LATTICE="inhomogeneous simple cubic lattice"; L=5; MODEL_LIBRARY="models.xml"; MODEL="hardcore boson"; t = 1.0; T = 0.1; delta=10.0; SWEEPS=500000; THERMALIZATION=10000; EPSILON=0.25; { DISORDERSEED = 34275; mu=delta*2*(random()-0.5); } My question is: why this stiffness is larger than one? Is there some scaling prefactor in front? Thank you in advance!
