MMWAVE-SDK: Phase difference for finding Z-axis and X-axis

I have two questions below.

(1) When finding the Z axis
The following modules are used when obtaining the Z axis, but the values of the peakAzim and peakElev series are
Is it possible to check without visualizer?

Wz = atan2(peakAzimIm * peakElevRe - peakAzimRe * peakElevIm,
peakAzimRe * peakElevRe + peakAzimIm * peakElevIm)/PI_ + (2 * Wx);

(2) When obtaining the X-axis
The following modules are used when obtaining the X axis, but sMaxIdx and DPU_AOAPROCDSP_NUM_ANGLE_BINS
Is it possible to check the value?

Wx = 2 * (float) sMaxIdx / DPU_AOAPROCDSP_NUM_ANGLE_BINS
