abtem.tilt.precession_tilts(precession_angle, num_samples, min_azimuth=0.0, max_azimuth=6.283185307179586, endpoint=False)[source]#

Tilts for electron precession at a given precession angle.

Parameters:
  • precession_angle (float) – Precession angle [mrad].

  • num_samples (int) – Number of tilt samples.

  • min_azimuth (float, optional) – Minmimum azimuthal angle [rad]. Default is 0.

  • max_azimuth (float, optional) – Maximum azimuthal angle [rad]. Default is $2 pi$.

  • endpoint (bool) – If True, end is max_azimuth. Otherwise, it is not included. Default is False.

Returns:

array_of_tilts – Array of xy-tilt angles [rad].

Return type:

2D array
