Problem description: AOA performance are highly deviated while working with AOA_ANGLE_MODE in angles around 15 degress and below. 

one can observe the deviation by looking at the graphs ans at the statistics csv at the RMS column.

The results contains results from both antenna arrays (mainly array #1)
