void GoldenPattern::addCount	(	unsigned int	iRefLayer,
		unsigned int	iLayer,
		const int	refPhi,
		const OMTFinput::vector1D &	layerHits
	)

Add a single count to the relevant pdf bin in three dimensions.

For making the patterns take events with a single hit in each layer

Shift phiDist so it is in +-Pi range

Shift phidist, so 0 is at the middle of the range

Check if phiDist is within pdf range in -64 +63 U2 code Find more elegant way to check this.

void GoldenPattern::normalise

(

unsigned int

nPdfAddrBits

)

Normalise event counts in mean dist phi, and pdf vectors to get the real values of meand dist phi and probability. The pdf width is passed to this method, since the width stored in configuration is extended during the pattern making phase.

Mean dist phi

Probabilities. Normalise and change from float to integer values

If there are only a few counts in given measurement layer, set pdf value to 0

Digitisation Values remapped 0->std::pow(2,nPdfValBits) minPlog->0

Make sure digitised value is saved using nBitsVal bits

Shift pdf index by meanDistPhi
