Is there a distinction between angular resolution and angular discrimination?

TL;DR

My understanding is that the terms are synonymous but I'm just wondering if there is a subtle difference between the two terms which I am unaware of.

Although essentially synonamous, the usages are somewhat different. Discrimination refers to difference, while resolution is about size.
