Leading order scaling corrections are studied using the finite size scaling method. We compute the corrections to scaling exponent $ω$ with high precision. We determine the value of the coupling $λ$ at which leading order corrections to scaling vanish. Using this result we obtain estimates for critical exponents that are more precise than those obtained with field theoretic methods.20 pages, two figures; numbers cited from ref. 23 corrected, few typos correctedHigh Energy Physics - LatticeStatistical Mechanicstext
