Version	v7r3
Release Date	13 February 2003
Description	Supports reading of OO-DST files only. Support reading of Winter 2003 production, Xmas 2002 production and Summer 2002 production data. Reading of  RAWH files is NOT supported by this version (use Brunel) The full chain from reconstruction objects to Particles and association to MCtruth is available for all type of Particles. Various types of ParticleMakers for particleID with different detectors are available.   Respect to v7r2: - new choice of database dependent configuration in DaVinci.opts for Winter data (DaVinciv254r1.opts)  - new algorithm for primary vertex determination (old one removed) in new packages PrimVtx. - new algorithm for reading results of Brunel Ks reconstruction - new tuning for L0 and L1 reprocessing identical to Winter production. - new tools for making Photons (the old one is kept) - modification in Efficiency algorithm for MC truth analysis  - new package MCTools to hold tools for analysis of MC truth with release of Visible Primary Vertex tool   Non-optimized versions of various offline physics selection for performance studies are available in the PhysSelections package. None have been modified repect to v7r2. The following can run on OO-DST files: Bd -> D0 bar ( K pi ) K* ( K pi ) Bs -> mu mu  Bs -> Ds ( K K pi) K Bs -> Ds ( K K pi) pi       Bs -> J/Psi (mu mu) phi ( K K ) Bd -> J/Psi (mu mu) Ks ( pi pi ) Bd -> mu mu K*(K pi)      Bd -> pi pi Bs -> J/Psi (e e) phi ( K K ) Bd -> D ( K pi pi) D ( K pi pi) Bs -> Ds( K K pi) Ds( K K pi) Bd -> K* ( K pi ) gamma      Bd -> phi ( K K ) Ks ( pi pi ) pi0 ->gamma gamma      It is possible to configure tools making use of a Transporter to choose the concrete type to use. Associators for all type of ProtoParticles and for CompositeParticles following the links of the products are available. A first version of an algorithm to evaluate efficiencies for physics selections is available. The FlavourTagging package is recommended for use only by experts at the moment.
