But, those lines don't seem to conform to the rules typically used in thin lens ray traces. An example of which is below:

The video below describes the nature of the chief and marginal rays. It says, among other things, that marginal rays start at the bottom of the image and chief rays start at the top. It even passingly describes the exit angle of the marginal ray as being a function of the F-Number of the lens. The problem is he doesn't go into much detail and I havent been able to corroborate the equation with another source.

As for the second half of the trace: if the chief ray passes the aperture stop on the optical axis, then it must also pass the "image" of the aperture stop at that place - which gives rise to the trace that gets you the rest of the image.

All you need to know about the chief ray is that it will show up in the right place at the focal plane. Any path that gets there is valid. You will see that this is indeed the case for your example - the ray starts up at the top of the image (tip of the arrow) and passes through the tip of the arrow in the "internal image" plane.

Any pair of straight lines that gets from A to B is valid - although when you are trying to construct where the internal focal plane is, the construction as drawn is not useful, once you know where it is you can draw any of a family of lines, including the one shown.

The equations he presents are the literal mathematical relationships between incoming and out outgoing ray angles (of any type) and it has a spreadsheet linked to the bottom that walks through both chief and marginal ray examples. I say walk-through, but really you'll need to watch the video I linked to above and pay careful attention to the cell math in order to get whats going on (at least I did).

I did some digging and I found a blog that indirectly, but the none the less explicitly, talks about ray tracing chief and marginal rays in thin lens systems:

Provided you know the diameter and focal length of the lenses in a system, what are the rules for ray tracing the chief and marginal rays? If its even possible.
