HERA Tool: File Plot 2
The periodicity on this plot for this binary system, or any plot with only 100 rows isn't easy
to see. Experiment with more rows until you find out how much time, i.e., how many rows, you need
to best estimate the periodicity. It will take a while to plot lots of data -- be patient! When you decide on the clearest choice of rows to estimate the period, print it out.
