Data of "Evolution of microstructural properties in sheared iron-rich olivine"

There are data for 5 samples, 248, 263, 278, 303 and 345.Files named by "PTXXX_fine_clean.ctf" are orientation data for sample XXX obtained by EBSD with fine step size (1.5 micron). The data have gone through noise reduction process in HKL channel5 software. Files named by "PTXXX_whole_clean_rot.ctf" are orientation data for sample XXX obtained by EBSD with coarse step size to cover the whole radial section. The data have gone through noise reduction process in HKL channel5 software. The orientation of each pixel have been rotated for shearing top to the right. <br>Files named by "PTXXX_fine_data.mat" are processed data of the map with fine step size for sample XXX. The data can be opened by MATLAB software. The meanings of major variables in the data are listed in file "Variables in fine processed data.docx"<br>Files named by "PTXXX_whole_polefigures.zip" are processed pole figures across the whole radial section for sample XXX. Each file in the compressed folder is named as "PTXXX_whole_pole_YYY", where YYY is the distance from the axial center of the sample (in mm).

本数据集共包含5个样本的数据，样本编号分别为248、263、278、303及345。
以"PTXXX_fine_clean.ctf"命名的文件，为采用精细步距（1.5微米）电子背散射衍射（Electron Backscattered Diffraction, EBSD）采集得到的样本XXX取向数据，该数据已通过HKL Channel5软件完成降噪处理。
以"PTXXX_whole_clean_rot.ctf"命名的文件，为采用粗步距采集以覆盖整个径向截面的样本XXX取向数据，该数据同样已通过HKL Channel5软件完成降噪处理，且已对所有像素的取向执行旋转操作，以实现顶部向右的剪切校正。
以"PTXXX_fine_data.mat"命名的文件，为样本XXX精细步距取向图的后处理数据，可通过MATLAB软件打开。该数据中主要变量的含义已在文档"Variables in fine processed data.docx"中详细说明。
以"PTXXX_whole_polefigures.zip"命名的压缩包，为样本XXX覆盖整个径向截面的极图后处理数据。压缩包内的每个文件均以"PTXXX_whole_pole_YYY"命名，其中YYY代表该位置到样本轴向中心的距离（单位：毫米）。
