IGOR Pro

IGOR Pro is a scientific data analysis software, numerical computing environment and programming language that runs on Windows or Mac operating systems.

It is developed by WaveMetrics Inc., and was originally aimed at time series analysis, but has since then evolved and covers other applications such as curve fitting and image processing.

IGOR Pro is primarily known for its graphics capabilities, and like Origin and other similar programs, is often used to generate plots for scientific and other publications.

Several large scientific user facilities, such as Argonne National Laboratory, have developed and published data analysis libraries for Igor Pro.

[5][6][7] The control and data-acquisition programs for photoelectron spectrometers of ScientaOmicron [8] and SPECS Surface Nano Analysis GmbH[9] save spectra in Igor Pro file formats.
