Unfolding the paper reveals a diagram written in, what, is that some kind of green marker?

In bright green marker is [url=https://i.imgur.com/4dVYalX.jpg]a crude drawing[/url] of an oval with several lines drawn through it, a line going down through the circle with a sort of hooked end with an arrow is drawn pointing down along its length. Further down the paper is another line with a circle at one end and kind of a jagged edge coming off the top side of the line? Another arrow points at the circle with the jagged line sticking out.
