I don't have a diagram, but it's a straightforward character. The premaxilla has a ventral margin (along the tooth row) and an anterior margin (that forms the front of the snout). The character has do do with the angle between those two margins.

Hello
I'm pouring over your paper on phylogeny tyrannosauroid dinosaurs as part of my thesis work on computational modeling for the creation of phylogentic graphs. I'm not understanding what you are measuring in characteristic 13. Do you have an example of a diagram of what is being measured?
(Premaxilla orientationa nd shape of anterior margin)
I don't know what ventral and anterior margins are and what angle is being measured.
