bilby.gw.geometry.calculate_arm

bilby.gw.geometry.calculate_arm(arm_tilt, arm_azimuth, longitude, latitude)

Calculate arm unit vector from tilt, azimuth, and location.

Parameters:

arm_tilt: float or array-like

Tilt angle of the arm from horizontal in radians.

arm_azimuth: float or array-like

Azimuth angle of the arm in radians.

longitude: float or array-like

Longitude of the detector in radians.

latitude: float or array-like

Latitude of the detector in radians.

Returns:

array-like

3D unit vector (shape (3,) or (3, …)) representing the arm direction.
