si_wafer# bool = False, show_progressbar: bool | None = None, **kwargs) EBSD[source]#

EBSD dataset of (50, 50) patterns of (480, 480) pixels from a single crystal silicon wafer, acquired on a NORDIF UF-420 detector [Ånes et al., 2022].

The dataset was acquired in order to test various ways to calibrate projection centers (PCs), e.g. the moving-screen PC estimation technique [Hjelen et al., 1991]. The EBSD pattern in silicon_ebsd_moving_screen_in() is from this dataset.


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


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


Keyword arguments passed to load().


EBSD signal.
