Detailed Description

Data preparation algorithm that transforms the uncalibrated measurements into muon space points.

Mdt, Mm measurements are directly transformed. The remaining three technologies provide eta & phi measurements, each 1D. The measurements are sorted by gas gap and if the occupancy in the gas gap is low enough, then each eta measurement is combined with each phi measurement to a 2D space point. Otherwise, single 1D space points are produced. Space points in the same MS layer & phi-sector are expressed in the common sector frame.

distributePhiPoints()

void MuonR4::SpacePointMakerAlg::distributePhiPoints ( std::vector< SpacePoint > && spacePoints, SpacePointBucketVec & splittedContainer ) const

private

Distributs the vector phi space points into the buckets.

In contrast to the primary distribution no new buckets are created and the points are distributed into the existing ones instead.

Parameters

spacePoint	Vecotr of phi space points to sort into the buckets
splittedContainer	Output vector containing all defined bucket

If maxY is smaller than the lower cov boundary or minY is bigger than the other boundary, there's definetely no overlap

distributePointsAndStore()

void MuonR4::SpacePointMakerAlg::distributePointsAndStore ( SpacePointsPerChamber && hitsPerChamber, SpacePointContainer & finalContainer ) const

private

Distribute the premade spacepoints per chamber into their individual SpacePoint buckets.

A new bucket is created everytime if the hit to fill is along the z-axis farther away from the first point in the bucket than the <spacePointWindowSize>. Hit in the previous bucket which are <spacePointOverlap> away from the first hit in the new bucket are also mirrored. The bucket formation starts with the eta Muon space points and then consumes the phi hits.

Parameters

ctx	Event context of the current event
hitsPerChamber	List of all premade space points which have to be sorted
finalContainer	Output SpacePoint bucket container.

Order the space points by local chamber y which is along the tube-plane.

loadContainerAndSort() [1/2]

template<typename ContType>

StatusCode MuonR4::SpacePointMakerAlg::loadContainerAndSort ( const EventContext & ctx, const SG::ReadHandleKey< ContType > & key, PreSortedSpacePointMap & fillContainer ) const

private

Retrieve an uncalibrated measurement container <ContType> and fill the hits into the presorted space point map.

Per associated MuonChamber, hits from Tgc, Rpc, sTgcs are grouped by their gasGap location and then divided into eta & phi measurements. If both are found, each eta measurement is combined with phi measurement into a SpacePoint. In any other case, the measurements are just transformed into a SpacePoint.

Parameters

ctx	Event context of the current event
key	ReadHandleKey to access the container of data type <ContType>
fillContainer	Global container into which all space points are filled.

Loop over the chamber hits to split the hits per gasGap

Fill in the 2D measurements BIL Rpc

Only one dimensional space points can be built

Simple combination by taking the cross-product

There's no valid combination with another phi hit

Tgc measurements with different bunch crossing tags cannot be combined

Helper function combine an eta and a phi collection. The function takes two indices referrring to the indices of the hit vector inside HitColls

Parameters

collIdxA	Index of the collection to put as phi
collIdxB	Index of the collection to put as eta
combFunc	Lambda function that rejects hits which cannot be combined due to geometry reasons.

Skip if one of collections are empty

Get first hit from the first collection

The hit in the collection has already been used
