ExtractRoadID()

int UtilTrigger::ExtractRoadID

(

const SQHitVector *

vec

)

Find a unique road in the given list of SQHits.

This function returns a road ID if the given list contains exactly one hit every top plane (i.e. H1T, H2T, H3T & H4T) or every bottom plane. It returns '0' if any plan has no hit or multiple hit. The given list can contain any extra Y-hodoscope, chamber or prop tube hit, which is just ignored.
