HRRY-spectral and related terms: A refined nomenclature for high repetition rate hyperspectral systems

► Provides a comprehensive list of measures that may compare spectroscopic systems. ► Thoroughly reviews spectral measures such as the 'spectral resolution element'. ► Proposes 'HRRY-Spectral' to describe systems achieving high spectral data rates. ► Compares commercial spectroscopic systems to each other and to the Fourier Limit.
