- kikuchipy.data.ni_gain(number: int = 1, allow_download: bool = False, show_progressbar: bool | None = None, **kwargs) EBSD #
EBSD dataset of (149, 200) patterns of (60, 60) pixels from polycrystalline recrystallized Ni, acquired on a NORDIF UF-1100 detector [Ånes et al., 2019].
Ten datasets are available from the same region of interest, acquired with increasing gain on the detector, from no gain to maximum gain.
Dataset number 1-10. The camera gains in dB are 0, 3, 6, 9, 12, 15, 17, 20, 22 and 24. Default is dataset number 1, acquired without detector gain.

The datasets are hosted in the Zenodo repository https://doi.org/10.5281/zenodo.7497682 and comprise about 100 MB each as zipped files and about 116 MB when unzipped. Each zipped file is deleted after it is unzipped.
