Member Enumeration Documentation

HitWindow

enum MuonR4::NswSegmentFinderAlg::HitWindow

strongprivate

To fastly check whether a hit is roughly compatible with a muon trajectory a narrow corridor is opened from the estimated beamspot to the first tested hit in the seed finding.

Hits in subsequent layers need to be within this corridor in order to be considered for seed construction. The HitWindow is the output classification of such a corridor test.

Enumerator
tooLow
inside	The hit is below the predefined corridor.
tooHigh	The hit is inside the defined window and hence an initial candidate.

Definition at line 131 of file NswSegmentFinderAlg.h.

Enumeration to classify the orientation of a NSW strip

Enumerator

Construct a set of prelimnary seeds from the selected combinatoric layers.

Quadruplets of hits, one from each layer, are formed if they are all within the the corridor as described above

Parameters

beamSpot	Position of the beam spot in the sector's frame
combinatoricLayers	Quadruplet of four hit vectors from which the hits are retrieved
usedHits	Mask marking hits that were already successfully added to a seed
outVec	Reference to the output vector where the initial seeds are stored. The vector is cleared at the beginning and capacity is allocated accordingly

Assign enough memory to the vector

The hit is alrady in a good seed. Don't consider again

Construct the beamspot to first hit connection to guestimate the angle

Apply cut window on theta of the seed.

inlineprivate

The hit is above the predefined corridor.

Tests whether a hit is inside the corridor defined by line connecting the centre of the first candidate hit in the seed and the beam spot. The theta angle is varied by m_windowTheta to define the lower & upper direction etimate. The function tests whether the strip then crosses the corridor.

Parameters

testHit	Reference to the hit to test
beamSpotPos	Position of the beam spot serving as starting point
dirEstUp	Direction vector defining the upper limit of the corridor
dirEstDn	Direction vector defining the lower limit of the corridor

Calculate the strip edges

Check whether the both edges are below the lower estimated muon arrival

Analogous check for the upper edge

No extrapolation needed
