AL for W+, W- from SL09g, Run 9, after Q/PT cut (take3)

 This is another (3rd) spin sorting of pp500 Ws from Run 9, January 27, 2009

The following changes to W-algo & spin sporting were made since previous spin-sort:

1) use pT-balance cut; 
2)drop undecided Q/PT , symmetric; 
3) extend ET range down to [25,50] GeV; 
4) lepton |eta|<1
5) use new lumi monitor : events with 2x2 ET <20 GeV and  ET 2x2/4x4 < frac24

 Detailed table with yields & intermediate results is in attachment A)

Note, all errors are computed approximately based on total # of unpolarized events.
