GetSlope()

float PndFtsTrackFinder::GeomUtil::GetSlope

(

const uint8_t

layerId

)

Auxiliary function to get a slope of the given layer in degrees. Possible slope values are: 0, 11.43 or -11.43 deg. Layers 3, 4, 11, 12, 19, 20, 27, 28, 35, 36, 43, 44 have negative slope. Other fSkewed layers have positive slope. Vertical layers have no slope.

Parameters

layerId

id (number) of the layer

Returns

slope of the straws in the given layer

GetStationFromLayer()

PndFtsStation PndFtsTrackFinder::GeomUtil::GetStationFromLayer ( const uint8_t  layerId )

noexcept

Auxiliary function to get a station containing the given layer. Each FtsStation contains 16 layers.

Parameters

layerId

id (number) of the layer

Returns

FtsStation containing the given layer

GetStationFromStraw()

PndFtsStation PndFtsTrackFinder::GeomUtil::GetStationFromStraw ( const uint16_t  strawId )

noexcept

Auxiliary function to get a station containing the given Straw.

Parameters

strawId

id (number) of the straw

Returns

FtsStation containing the given Straw

IsOutermostLayer()

bool PndFtsTrackFinder::GeomUtil::IsOutermostLayer

(

const uint8_t

layerId

)

Auxiliary function to check whether the given layer is fOutermost layer. Outermost layers are: 1, 2, 3, 4, 13, 14, 15, 16, 17, 18, 19, 20, 29, 30, 31, 32, 33, 34, 35, 36, 45, 46, 47, 48.

Parameters

layerId

id (number) of the layer

Returns

true if the given layer is fOutermost, false otherwise

IsSkewedLayer()

bool PndFtsTrackFinder::GeomUtil::IsSkewedLayer

(

const uint8_t

layerId

)

Auxiliary function to check whether the given layer contains fSkewed (layer is fSkewed) or vertical straws. Skewed layers are: 3, 4, 5, 6, 11, 12, 13, 14, 19, 20, 21, 22, 27, 28, 29, 30, 35, 36, 37, 38, 43, 44, 45, 46.

Parameters

layerId

id (number) of the layer

Returns

true if straws in the given layer are fSkewed, false if vertical
