Class UnassociatedHits

java.lang.Object
  hep.lcd.util.driver.AbstractProcessor
      hep.lcd.contrib.recon.tracking.garfield.UnassociatedHits

All Implemented Interfaces:

Processor

public final class UnassociatedHits

extends AbstractProcessor

Provides list of hits which are not associated to standard tracks. Also purges hits from the list of unassociated hits which are to close (200 microns) to each other)

Known quick fixes:
- hitOnTrack: uses Monte Carlo info instead of hits to tracks pointer which is non-existent - will be corrected once we move to LCIO
- alreadyInList: quick fix instead of a decent hit Clustering algorithm. alreadyInList() simply dropps hits if they are too close to previously added hits

Known dependencies on SD or hep.lcd
- codeVXD = 1 for VTX hits is used
- distance of 200 miocrons is hardcoded in code (variable distCut)

process

public void process(LCDEvent event)

Description copied from interface: Processor

Called by the driver when this processor should process an event. If the processor produces new output it should add it to the event.

Parameters:

event - The event to process
