We have studied the spectrum on lattice sizes 83, 103, 123, and 164 × 24 for 6/g2 = 5.445 and amq = 0.025. We find small finite size effects. With much smaller errors than earlier results, we find no improvement in the Edinburgh plot as the lattice spacing decreases from ≈ 0.25 fm to ≈ 0.15 fm. The improved values of the rho and nucleon masses allow a more precise determination of the temperature of chiral symmetry restoration.
