Looking at Hubble through the Eyes of JWST

Abstract :
The phase retrieval algorithm developed for the James Webb Space Telescope (JWST) is applied to archival image data that was originally used to characterize the Hubble Space Telescope (HST) primary mirror edge defect. The value obtained for the spherical aberration is compared with earlier values reported by several teams comprising the Hubble Aberration Recovery Project (HARP). Several lessons learned from the Hubble phase retrieval problem are described and a discussion is given on how these have been incorporated into the JWST Observatory design.
