Abstract :
The results of comparisons of the performances of several tracking and/or analysis codes are presented. The basic purpose of this program was to assess the reliability and accuracy of these codes, i.e. to determine the so-called error bars for the predicted values of tunes and other lattice functions as a minimum and, if possible, to discover potential difficulties (inadequate algorithms, residual bugs, etc.) with the underlying physical models in these codes. Not only was it possible to determine the error bars, which, for instance, for the tunes at dp/p=+1% are Δνx=0.0027, Δνy=0.0010, but also the program has brought about improvements of several codes
