A histogram was made for each year showing the numbers of zaps in each period bin.
Models of the radars were made to shows what frequencies their
PRF'S (Pulse Repetition Frequencies) would create.
The radar periods were then over plotted on the zaplist data.

These summary plots were generated by the
p2030 group (most likely patrick...). I've added comments on when
