DOA array value scale

Hello!

I am having trouble understanding what scale the DOA is given in.

What is the scale of these values? Are they dB? Degrees? Some other arbitrary scale?

The DOA is returned as an array of values with 0 indicating the strongest direction and the larger values represent weaker signal. They are easy to implement, but hard for me to understand.

Thank you for the Kraken-team for a great product and the community for support.
