Hubble Space Telescope Faint Object Camera calculated point-spread functions

Hollis, J. M.; Dorband, J. E.; Lyon, R. G.

A set of observed noisy Hubble Space Telescope Faint Object Camera point-spread functions is used to recover the combined Hubble and Faint Object Camera wave-front error. The low-spatial-frequency wave-front error is parameterized in terms of a set of 32 annular Zernike polynomials. The midlevel and higher spatial frequencies are parameterized in …
