Aphrodite, Artemis or a nymph?

I took this picture in Derbyshire, at Chatsworth House. It is one of the many sculptures they had there of Greek or Roman influences. They had lots of mythological figures, which I can generally identify easily, as I am a Greek mythology buff. This one is a bit challenging. She could be Aphrodite, as she is often depicted nude. Or she could also be Artemis, as she is being spied by Actaeon. But they already had an Artemis. I am wondering if she could merely be a nymph of some sort. They tend to be depicted at their bath or as they are drying up. What do you think?
