PIVA - Photoemission Interface for Visualization and Analysis

PIVA is a graphical user interface (GUI) application built with PyQt5 and pyqtgraph toolkits, designed for the interactive and intuitive examination of large image-like datasets. While it can display any multidimensional data, most of its functionalities are specifically tailored for users conducting Angle-Resolved Photoemission Spectroscopy (ARPES) experiments.

A variety of standard methods and image processing algorithms (such as momentum-space conversion, energy distribution curve symmetrization, and derivative analysis) are available directly from the GUI. Additionally, several utilities are particularly useful during the experimental phase when decisions about subsequent steps need to be made quickly. These utilities include automated methods for locating the highest symmetry points, azimuthal rotation, and autogenerated experimental notebooks. These features are implemented for various beamlines at different synchrotron sources around the world.
