Detailed Description

Wire hit relation filter that is compensating for hit inefficiencies.

The default setup counters some hits lost due to a drift time cut off if the track enters at the edge of a drift cell. The biggest effect observed in the CDC simulation was observed when the track is along the 2, 4, 8 and 10 o'clock direction since in this case two neighboring hits can be lost due to this time cut off. In an attempt to detect if this occurred the primary wire hit neighborhood is slightly extended to bridge to the secondary neighborhood in the critical directions.

The criterion can be lowered such that fewer missing hits trigger the inclusion of the secondary neighbors.
