1. Purpose of the program JECP/SP is a computer program in Java Electron Crystallography Package. JECP is developed for quantitative electron diffraction and image processing, the package is designed and written by Dr. XingZhong Li. JECP/SP provides the all necessary functions of stereographic projection for regular application and furthermore it can be used to minimized the difficulties encountered when tilting highly beam-sensitive, or small-grain-size specimens with known structures using either a double-tilt or a rotation holder. JECP/SP can be used as a teaching aid for students on fundamental crystallography as well as a tool for scientists working on TEM experiments.
