Figure 1a: Sensitivity of zeros for coefficients 1/1 
The zeros colored by their
sensitivity to variation in the coefficients of the polynomial. The
sensitivity is cumulative over all the coefficients. The color scale
represents a normalized sensitivity to the range of values; red is
insensitive to violet which is strongly sensitive. All zeros are pictured.
The zeros are for coefficients 1 and +1 for polynomial degree 17.

Figure 1b: Density of zeros for coefficients 1/1 
The zeros are colored by their
density. The distribution of zeros has been coarsened by collecting
them onto a grid, resulting in a slight blockiness. The range of
color is normalized to the range of densities; red is low density to
blue which is high density.

Figure 1c: Sensitivity of zeros relative to coefficient a_{1} 
Figure 1a is reproduced, this time with conditioning relative to the
coefficient for x.

Figure 1d: Sensitivity of zeros relative to coefficient a_{9} 
Figure 1a is reproduced, this time with conditioning relative to the
coefficient for x^{9}.

Figure 1e: Sensitivity of zeros relative to coefficient a_{16} 
Figure 1a is reproduced, this time with conditioning relative to the
coefficient for x^{16}.
