accuracy

Does anyone know the proper interpretation of the accuracy measurements returned by getAccuracy()? For instance, are they calculated as:

Circular Error Probability (meaning, if i understand correctly, radius of a 50% confidence circle)?
Radius of 95% confidence circle?
something else?

Many thanks for any advice you can give me.
