◆ CalculateChannelOffsets()

XPU_D void sts::Hitfinder::CalculateChannelOffsets ( FindClusters::context & ctx,
CbmStsDigi * digis,
unsigned int * channelOffsets,
unsigned int nDigis ) const
private

sts::Hitfinder::calculateChannelOffsets Calculates the Offsest of every channel. digis-Array is sorted in Channel and Time. If a channelChange is detected it is stored in channelOffsetsPerModule.

Parameters
digisAll Digis that are relevant for this Block
channelOffsetsThe Array where all offsets are written to
nDigisAmount of digis in digis-Array

sts::Hitfinder::calculateClustersDigiWise

Each Thread one Channel

ChannelId: 00000 11111 DigiIndex: 01234 56789 ThreadId: 01234 56789

Calculates the Clustercharges of all found ClusterConnections. Each Thread takes on digi and looks for connections. When the thread is done, it takes the next digi. If one Digi does not have a previous one it's a cluster start and may be the start of either a single-element-cluster, double-element-cluster or multi-element-cluster.

Parameters
digisAll Digis that are relevant for this Block
digiConnectorArray where the connection between 2 digis is sotred in.(next Digi; has Previous)
iModuleThe Module that the curren Block is working on
threadIdId of the thrad currently working
