!       93-95: Muon+Electron PRL 
!       96-98: Muon only from Giulia's thesis 
! D*,D  93-98: PRD publication  exclusive D*+,D and inclusive D*.
! K+Vtx 96-98: Revised 96-98 R17 analysis
!
! No statistical correlation is assumed between any analyses
! except the exclusive D*,D & soft-pi* overlaps are removed to combine 
! into one "D*,D" number.
