REAL,ALLOCATABLE ::& vert(:,:),& ! True production vertex position of ! particle iprf(:,:),& ! True and Seen impact parameter in Rphi. ! True value has geometric sign; seen ! value (calculated by a call to ! ZAUCIP) can have geometric or ! life-time sign, depending on how ! ZAUCIP was called. ipz(:,:),& ! True and seen impact parameter in z. Ditto eiprf(:),& ! Seen error on impact parameter in Rphi. ! Calculated by ZAUCIP eipz(:),& ! Seen error on impact parameter in z. Ditto. par(:,:),& ! Seen track parameters at perigee: ! Par(1) = Impact-parameter in Rphi,& ! with geometric sign ! Par(2) = Impact-parameter in Z ! Par(3) = theta ! Par(4) = phi at perigee ! Par(5) = 1/Radius of curvature ! PAR is identically zero for particles ! only seen by calorimeters. wgt(:,:) ! Seen weight matrix of track parameters ! at perigee, in packed form ,ie. ! the elements of WGT are in the ! following positions in the symmetric ! 5X5 weight-matrix : ! ! 1 2 4 7 11 ! 2 3 5 8 12 ! 4 5 6 9 13 ! 7 8 9 10 14 ! 11 12 13 14 15 ! !

INTEGER,ALLOCATABLE ::& hitbar(:,:),& ! bitted word telling what detector hitfwd(:,:) ! layers measured the track parameters: ! if barrel layer i was hit, bit i is ! set in HITBAR, and if forward layer ! i was set, the bit is set in HITFWD. ! Use the bit-handling routines in ! the utilities patch GENUTL ! ! Use the access-routines in SGVTRKER ! to find out more information on the ! layer. Eg.
