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
and10
).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.
