si_ebsd_moving_screen#

kikuchipy.data.si_ebsd_moving_screen(distance: int = 0, allow_download: bool = False, show_progressbar: Optional[bool] = None, **kwargs) → EBSD[source]#

One EBSD pattern of (480, 480) pixels from a single crystal silicon sample, acquired on a NORDIF UF-420 detector [Ånes et al., 2022].

Three patterns are available from the same sample position but with different sample-screen distances: normal position (0) and 5 mm and 10 mm greater than the normal position (5 and 10).

They were acquired to test the moving-screen projection center estimation technique [Hjelen et al., 1991].

Parameters:
distance

Sample-screen distance away from the normal position, either 0, 5 or 10.

allow_download

Whether to allow downloading the dataset from the internet to the local cache with the pooch Python package. Default is False.

show_progressbar

Whether to show a progressbar when downloading. If not given, the value of hyperspy.api.preferences.General.show_progressbar is used.

**kwargs

Keyword arguments passed to load().

Returns:
ebsd_signal

EBSD signal.
