Measurement of the W-pair Production Cross-section and W Branching   Ratios in e+e- Collisions at sqrt(s) = 161-209 GeV
  These final results on e+e- -> W+W- production cross-section measurements at LEP2 use data collected by the DELPHI detector at centre-of-mass energies up to 209 GeV. Measurements of total cross-sections, W angular differential distributions and decay branching fractions, and the value of the CKM element |V_{cs}| are compared to the expectations of the Standard Model.   These results supersede all values previously published by DELPHI.
