TL;DR: The GMT-CfA, Carnegie, Catolica, Chicago Large Earth Finder (G-CLEF) is a fiber fed, optical echelle spectrograph that has undergone conceptual design for consideration as a first light instrument at the Giant Magellan Telescope as discussed by the authors.

TL;DR: In this paper , the authors characterize the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period, with an emphasis on differences from pre-launch expectations.

TL;DR: A wave front error budget has been developed to help define the technology needs and assess performance, and includes both spatial and temporal domain aspects for the active, adaptive and passive elements in the optical design.

TL;DR: The James Webb Space Telescope (JWST) as discussed by the authors is a large, infrared space telescope that has recently started its science program which will enable breakthroughs in astrophysics and planetary science.
