    • Because the input is a scalar time series, we constrain the trajectory adjustment to yield a scalar time as output. For instance, if x1= ( ξi, ξ2) consists of the first two values in the time series, then the output begins with values ξ hat1, ξ hat2,ξ hat3 such that x hat1= ( ξ hat1, ξ hat2) , x hat2= ( ξ hat2, ξ hat3).

    • To save CPU time, a maximum of 200 points is used to compute the linear maps. Despite these constraints, it is never necessary to compute a one-dimensional map approximation for this attractor as described in the text.

    • When the program is run on noiseless input, the mean error in the output is 0.025% of the attractor extent, which suggests that errors arising from small nonlinearities are negligible when the input contains enough points.

    • In the noise reduction procedure, the attractor is reconstructed in four dimensions from a time series containing 32768 values. Linear maps are computed using at least 50 points in each ball. Trajectories are fitted using windows of 24 attractor points which overlap by 6 points.
