\r
5 File produced July 4, 2000
\r
6 The total impulse, peak thrust, average thrust and burn time are
\r
7 the same as the averaged static test data on the NAR web site in
\r
8 the certification file. The curve drawn with these data points is as
\r
9 close to the certification curve as can be with such a limited
\r
10 number of points (32) allowed with wRASP up to v1.6.
