Hee analysis at 189 GeV - an update
R.C . / F.F./R.M./P.M. - 8/2/99
Based on 98C2, old optimisation
New features: Data-MC  comparison  at preselction and after elid.: some discrepancy at presel.,  low statistics at el. id.

Loose btag cut at -1.8; focus on 2D  analysis
With the -1.8 btag cut 2 events survive
85393/5178 (cut by btag in previous analysis)
 85688/231  (lost for bad elec. energy determination in previous analysis)
