33. This peak frequency often does not agree perfectly with the frequency of one
of the component waves, as the very tip of the spectral peak often is located
at a frequency that falls ‘between’ two of the discrete frequencies for which
values of spectral power have been calculated. However, as more and more
discrete frequencies are plotted within a finite frequency band, this error will
become smaller and smaller.

36. The numbers on the vertical axes of our graphs disagree by a factor of 2.
This discrepancy appears to be the result of a normalization error on the part
of the Pacemaker authors. Apparently, they forgot to multiply their spectral
powers by 2 when converting from a two-sided power spectrum (negative
and positive frequencies) to a one-sided power spectrum (positive frequencies

Jake Hebert earned a B.S. from Lamar University, an
M.S. from Texas A&M University, and a Ph.D. from the
University of Texas at Dallas (all degrees in physics).
He studied optics at Texas A&M and was a 1995-96
Dean’s Graduate Fellow. His Ph.D. research involved a
study of the possible connection between fair-weather
atmospheric electricity and weather and climate. He
has taught at both the high school and university levels
and became a research associate at the Institute for
Creation Research in 2011, where his research interests
include climates before and after the Flood, cosmology,
and general apologetics.
