... 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. ...
