- Calculate the frequencies and powers for the Eccentricity data over the the last 1 Ma
- Plot the periodogram of Eccentricity
- The plot should have a log y-scale and a linear x-scale
- Set the limits of the x-axis to .001 and .06
- Set the limits of the y-axis to .00001 and .1
- Add labels to the axes
- Add a vertical line at 1/100 (the frequency of eccentricity)
- Add the text "100 kyr" above the vertical line
