◆ addHit()

void addHit	(	unsigned	iSL,
		int	iTS
	)

increase counter for super layer and track segment number in super layer.

track segment number can be negative. hits in the wrong hemisphere (not in [-nWires/4, nWires/4]) are skipped.

Definition at line 13 of file CDCTriggerMLPData.cc.

 {
   if (iSL < hitCounters.size()) {
     int N = hitCounters[iSL].size();
     // shift negative indices
     if (iTS < 0) iTS += N;
     // check the range
     //   0, N:        hit is on the track
     //   [0, N/4]:    hit is in quadrant left of the track
     //   [N/4, 3N/4]: hit is in hemisphere opposite of the track (skipped)
     //   [3N/4, N]:   hit is in quadrant right of the track
     if ((0 <= iTS && iTS <= N / 4) || (3 * N / 4 <= iTS && iTS < N)) {
       ++hitCounters[iSL][iTS];
     }
   }
 }

◆ getHitCounter()

unsigned short getHitCounter	(	unsigned	iSL,
		int	iTS
	)		const

get hit counter for super layer and track segment number is super layer.

track segment number can be negative.

Returns: counter or 0 (for invalid input)
