1. Wavefront Quality
... The measured wavefront errors in the four cameras were 1/30, 1/17, 1/40, and 1/21 waves at 6328е. The dominant problem was a small difference in focus between the four cameras (Krist and Burrows 1995). The actuated fold mirrors and pick-off mirror mechanism performed flawlessly in correcting residual coma aberrations in the image, and enabled the on-orbit alignment procedures. ...

... Complex astrophysical phenomena could now be studied spectroscopically: the X-ray absorption line forest intrinsic to Seyfert galaxies; the interaction between AGN jets and intracluster media; hot winds of starburst galaxies; stellar coronal plasmas; the charge -exchange emission of Mars' exosphere; the X-ray irradiation of protoplanetary disks; and the myst erious flat-topped spectral line shapes of O star winds. ... We estimate that Gen-X will be able to detect and resolve 20, 000 stars in NGC...
