You input what it is at the time you observe it. The TDC keeps track of it over time.

The AoB is the angle between the target's course and the target's line of sight to your position. On the drawing, it's listed as theta[bow] at the top-left corner. The top-right is the intercept of your course and the target course. If you use that angle, you will be using the wrong value.

From a video I watched ,,angle on the bow is where the other guy is looking at you from his bridge if he could see you.

That's what I was taught as a lookout in the bridge. A much simpler way of explaining it.
