Web1 gen 2024 · Modern ARPES data sets are almost always multidimensional, and sometimes incorporate four or more orthogonal dimensions. In this paper we will focus on 2D images with just a single momentum axis and a single energy axis, both for the sake of simplicity, and because this is the most common representation of ARPES measurements. WebIgor Pro’s wave abstraction proved to be incredibly useful in the analysis of physics data. Unlike some other disciplines, in physics it is import to keep track of the axis coordinates, dimensions, and units for volumetric data, especially in ARPES. One of the principal difficulties in making fluent and natural data analysis suites for ARPES ...
