What is the aspect ratio of T-tail for common twin turboprops? I'm trying to figure out typical AR values for a T-tail configuration (at the conseptual design phase). Working with Raymer I found this table:

I can see the typical AR values for the vertical tail but I cant find anything about the horizontal one. The only info that I got is that it should be lower than wing's AR. The aircraft that I'm interested about is a twin turboprop.
Hmmmm.
