pyacs.lib.gmtpoint.pole

Euler pole prediction for GMT_Point.

pyacs.lib.gmtpoint.pole.pole(self, W=None, SW=None, type_euler='rot', option='predict')[source]

Apply or remove an Euler pole prediction to this point’s velocity.

Parameters:
  • W (array_like) – Euler pole: [lon, lat, omega] (deg/Myr) or [wx, wy, wz] (rad/yr).

  • SW (array_like, optional) – Variance-covariance of pole (3x3). If provided, updates SVe, SVn.

  • type_euler (str, optional) – ‘euler’ (geographic) or ‘rot’ (cartesian rad/yr). Default is ‘rot’.

  • option (str, optional) – ‘predict’ (velocity = pole only), ‘remove’ (subtract), ‘add’. Default is ‘predict’.

Returns:

New point with modified velocity.

Return type:

GMT_Point
