The txvo-diraaensional S : 172 XY naodel is investigated xvith an extensive qtranttrrn lVIonteCarlo sitntrlation. The helicity utaodtrltrs is precisely estitnated throtrgh a contintrotrs-titne loopalgorithraa f'or systenaas Lip to 128 X 128 near and below the critical tetaaperattrre. The criticalteuaaperattrre is estimated 2lS V'KT : 0.3427(2).7. The olctained estitnates for the helicity naodtrltrsare well fitted by a scaling f'orraa derived froraa the Kosterlitz renoruaaalization grotrp eqtuation.Tlte validity of the Kosterlitz-Tlrotrless theory for this taaodel is confirmed.
