To examine the convergence of the algorithm. The initial value above was 
solved using the 0.001, 0.005, 0.010, 0.020, and 0.040 time steps. The 
finest resolution time series (0.001) was used as a standard and the values
of the coarser time step series were compared relative to the 0.001 series. 
<p>
The cumulative and average errors of the time series relative to the 
standard were calculated by an <A HREF="ecalc.html">error calculation 
program</A> and the results are shown <A HREF="1b.html">here.</A>
