From data corresponding to an integrated luminosity of View the MathML source taken during the View the MathML source run in 1997, DELPHI has measured the W mass from direct reconstruction of View the MathML source and View the MathML source events. Combining these channels, a value of View the MathML source is obtained, where fsi denotes final state interaction. Combined with the W mass obtained by DELPHI from the WW production cross-section and with the direct measurement at 172 GeV this leads to a measured value of View the MathML source, in good agreement with the Standard Model expectation. The width of the W boson is also measured, giving the value View the MathML source.
