nickel_ebsd_master_pattern_small#
- kikuchipy.data.nickel_ebsd_master_pattern_small(**kwargs) EBSDMasterPattern [source]#
(401, 401)
uint8
square Lambert or stereographic projection of the northern and southern hemisphere of a nickel master pattern at 20 keV accelerating voltage.The master pattern was simulated with EMsoft [Callahan and De Graef, 2013].
- Parameters:
- **kwargs
Keyword arguments passed to
load()
.
- Returns:
ebsd_master_pattern_signal
EBSD master pattern signal.

Initially generated using the EMsoft EMMCOpenCL and EMEBSDMaster programs. The included file was rewritten to disk with
h5py
, where the master patterns’ data type is converted fromfloat32
touint8
withrescale_intensity()
, all datasets were written withdict2h5ebsdgroup()
with keyword argumentscompression="gzip"
andcompression_opts=9
. All other HDF5 groups and datasets are the same as in the original file.Examples
Import master pattern in the stereographic projection
>>> import kikuchipy as kp >>> s = kp.data.nickel_ebsd_master_pattern_small() >>> s <EBSDMasterPattern, title: ni_mc_mp_20kv_uint8_gzip_opts9, dimensions: (|401, 401)> >>> s.projection 'stereographic'
Import master pattern in the square Lambert projection and plot it
>>> s2 = kp.data.nickel_ebsd_master_pattern_small(projection="lambert") >>> s2.projection 'lambert' >>> s2.plot()
