When ESRI tool "Calculate Grid Convergence Angle (Cartography)" is used to calculate line bearing or azimuth, is the bearing referenced to True North or Grid North?

Thanks Mapperz. My question should have been when the bearing of a line is calculated using the "Add Geometry Attribute (LINE_BEARING)" tool, is the bearing referenced to Grid North or True North? – Adeleke Adejobi Jul 3 '20 at 13:42

Existing field that will be populated with the true north calculation value in decimal degrees.
Note:
rotation_method (optional)
- GEOGRAPHIC —Angle is calculated clockwise with 0 at top. This is the default.
- ARITHMETIC —Angle is calculated counterclockwise with 0 at right.
- GRAPHIC —Angle is calculated counterclockwise with 0 at top.
