  Triple gauge boson couplings are measured from W-pair and single photon
events recorded by the OPAL detector at LEP at center-of-mass energies between
183 - 209 GeV with a total integrated luminosity of 680 inverse picobarns. Only
CP-conserving couplings are considered and SU(2)xU(1) relations between the WWZ
and the WWgamma couolings are used, resulting in four independent couplings.
Each coupling is determined in a separate fit, assuming the other couplings to
take their Standard Model values. Fits are also done allowing some of the
couplings to vary simultaneously. The results are compared with the Standard
Model predictions.
