Simple analysis programs to extract Bhabha, dimuon, q-qbar and b-bbar
cross-sections and asymmetries can be found on shift50 (not aloha) 
in the /aleph/bew area. They are described below. These are not the
official analysis programs of M.-N. Minard and E. Merle, but 
give very similar results and are easy to use.

 ========= /aleph/bew/selmu ====================================

   SELMU.JOB      : Job to select dimuon candidates.
   SELMU.CARDS    : Card file setting selection cuts.
   muon_ntuple.h  : File defining and describing ntuple ID=100 
                    for selected dimuons.
   truth_ntuple.h : File defining and describing ntuple ID=10  
                    for input dimuons at truth level.
   selmu.F        : Fortran for dimuon selection.

 ========= /aleph/bew/selhad ====================================

   Similar routines for q-qbar (and b-bbar) selection. 

 ========= /aleph/bew/sele ====================================

   Similar routines for Bhabha selection. 

 ========= /aleph/bew/cards ====================================

   FILI cards for input data and MC datasets.

 ========= /aleph/bew/plots ====================================

   selmu189_data.his  : Data 
   selmu189_dimu.his  : mu+mu- MC
   selmu189_ditau.his : tau+tau- MC
   selmu189_ee.his    : Bhabha MC

   mucross.kumac      : Paw kumac for calculating dimuon cross section 
                        and asymmetry.

 Then similar files for determining the q-qbar (b-bbar) and Bhabha 
 cross section and asymmetries.
