incident angle

[tweigel-dev]

Again, thanks for the great implementation of DoA and especially MUSIC,
I noticed at the original paper of MUSIC, that he used -180 to 180 to plot output of theta (incident angles).

your Documentation recommend to use 0 to 181.
I notice, that it makes a huge difference to choose -90 to 91 or 0 to 181.
If I try to use 0 to 360 or -180 to 180 like in the original paper i get mirrored result (axe at the center).

Details

Can you explain the mirrored behavior and which incident angle array i have to use ?

Thanks i advance
