... The well-known spherical aberration in the OTA primary mirror causes most of the light for stellar targets to fall in a large halo (Figs. 2 and 3). The PSF core has nearly the correct diameter, but contains only about 15%of the light. ... The variations with field position are a large effect for WFPC images (Fig. ... This ``breathing'' of the OTA has a noticeable effect on the PSF wings for WFPC data; the wings expand and contract on a timescale comparable to the orbit period. ...

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. ...
