What do you want to know about angles of convergence?
Convergence is when the meridians of longitude all meet up or CONVERGE. Namely at the poles the convergence is maximum and at the equator it is zero! You can tell then that convergency is a function of latitude!
You can calculate convergency by using a small formula:
Convergency= change in long x sin mean lat
Hope this helps. Best ask the JAA about why you need to know this!
