... The resolution element (one diode) for GHRS was matched to the width of the SSA. ... A delta-function spectra line observed through the SSA can be described by a Gaussian with a FWHM of about 0.925 diodes which is about 3.7 quarter-stepped pixels. ... Since an SSA spectrum is the best resolution we can obtain with GHRS, it is useful to describe the LSA LSF in terms of the SSA PSF. Consequently, we have measured the LSA-SSA differential LSF for a number of gratings and at a sample of wavelengths. ...

5. Towards a General Definition for Spectroscopic Resolution
... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...

7. Optical static Fourier spectrometer
Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
