netsse.tools.misc_func.ang_std(angles, unit='deg')

Calculates the circular standard deviation of an array of angular data.

This function properly handles the circularity of angles at 360 degrees. The standard “two-pass” computation is implemented.

Parameters:

• angles (array_like) – Array of angles.

• unit ({'deg','rad'}, optional) – Specifies the unit of the angles as 'rad' or 'deg'. The default is 'deg'.

Returns:

std_a – Circular standard deviation.

Return type:

float

ang_diff

Calculates the signed difference between two angles.

ang_mean

Calculates the mean angle from an array of angular data.

Example

>>> std_angle = ang_std(angles, unit='deg')
