Dear Users,
1. Several users have pointed out strange behavior of the transfer matrix and tracking in MULT. There were two issues:
a) Convergence of the expression of z, R*6, and R5* components was poor when K1 -> 0.
b) There were a few bugs in the expression of the transfer matrix, especially in R*6 and R5* components.
Thus tracking is affected by a), and the transfer matrix (consequently emittance, etc.) is affected by a) and b). These bugs can be serious when there is a finite orbit through the MULT. This is a common issue both in k64 as well as the legacy version.
