Consistent measurements of alpha(s) from precise oriented event shape distributions

Consistent measurements of alpha(s) from precise oriented event shape distributions

An updated analysis using about 1.5 million events recorded at root s = M-Z with the DELPHI detector in 1994 is presented. Eighteen infrared and collinear safe event shape observables are measured as a function of the polar angle of the thrust. axis. The
