void L1Algo::CATrackFinder ( )

The main procedure - find tracks.

arrays for copy from vStsHits only hits, which aren't used in created tracks

arrays for contain prepared information

array of hits uses on current iteration

buffer for copy

array of info for hits uses on current iteration

index of hit in vStsHits indexed by index of hit in vStsHitsUnused;

fill the arrays for the first iteration

hitDensity - square root of number of hits, helps to keep the number of hits per bin (sell of grid) the same

sort hits by grid and y/z

input: array of unused hits, unused points, RealIHit_v - array of initial hit indexes, grid, StsHitsUnusedStartIndex, StsHitsUnusedStopIndex - indexes of 1st and last hits on station, NStations - number of stations

input: 1st hit on station, number of hits on station

coefficient for size of region for attach new hits to the created track

Set correction in order to take into account overlaping and iff z. The reason is that low momentum tracks are too curved and goes not from target direction. That's why sort by hit_y/hit_z is not work idealy If sort by y then it is max diff between same station's modules (~0.4cm)

possible left hits of triplets are splited in portions of 16 (4 SIMDs) to use memory faster

CREATE doublets

middle hits indexed by number of doublets in portion(i1)

index in portion of singlets(i1) indexed by index in portion of doublets(i2)

number of doublets in portion

save triplets in vTriplets

save triplets in vTriplets with gaps

Find neighbours of triplets.
