JETSET algorithm LUCLUS from LUND

Input arguments:

ICLASS

described in 10.3.

MINCLU

Minimum number of clusters to be reconstructed. (if <0, work space momenta are used as a start) (usually=1)

DMAX1

Max. distance to form starting clusters (usually=0.25GeV)

DMAX2

Max. distance to join 2 clusters (usually=2.5 GeV)

MULSYM

• = 1 for symmetric distance criterion (usual)
• = 2 for multicity distance criterion

Results:

NJETS

is the number of ``jets''

• = -1 if not enough particles
• = -2 if not enough working space (KTBOMX)
TGEN
Generalized thrust
DMIN
Minimum distance between 2 jets
• = 0 when only 1 jet
• = -1 , -2 as for NJET
'name'
Vectors containing 4-momenta of the jets.
