This page is intended to be a repository of documents about the LHCb Muon data preparation.

The upgrade phase-1 of the LHCb detector foresees the readout of the detector at 30 MHz,
and the selection of partially reconstructed events at the 
HLT1 stage, to reduce the data flow 20-40 fold.

The muon data preparation code is under an important revision, the aim is
to reduce the computing time. The actual main changes are:

1)  code ported in the Gaudi Functional scheme;

2)  drop of the usage of KeyedContainer and reduced the access to TES;

3)  MuonCoord as an intermediate step has been completely removed;

4)  MuonRawBuffer, MuonRec and MuonPrepareHits codes have been replaced by
     MuonRawToHits;

5)  created a lookup table to replace Tile2XYZ;

6)  improve sorting.
