19. 1 is calculated here by adding in quadrature the longitudinal uncertainty in the positions of the primary and secondary vertices. The primary vertex had a typical uncertainty of .035 cm. The secondary vertex had a typical uncertainty of .036 cm for a 70 GeV/c D and the uncertainty increased roughly linearly with a slope of 0.003 cm per 10 GeV/c.
20. 1 here depends only on the longitudinal uncertainty in the position of secondary vertices as the target foil edge is taken to be known with infinite precision.
21. p is 0.0011 cm.
22. 1 is the resolution on the separation. In addition, the maximum allowed value for d is 0.005 cm.
23. t in GeV/c) increased from 2.0 to 5.0, and MSTP(92) (the remnant quark-diquark energy splitting function) changed from 4 to 3.
