TL;DR: The Keck Cosmic Web Imager (KCWI) as discussed by the authors is a general purpose optical integral field spectrograph that has been installed at the Nasmyth port of the 10 m Keck II telescope on Maunakea, Hawaii.

TL;DR: FOBOS, the Fiber-Optic Broadband Optical Spectrograph, is a near-term fiber-based facility that addresses spectroscopic needs by optimizing depth over area and exploiting the aperture advantage of the existing 10m Keck II Telescope.

TL;DR: FOBOS as discussed by the authors is a near-term fiber-based facility for the existing 10m Keck II Telescope, which has a uniquely blue-sensitive wavelength range (0.31--1.0 um), R ~ 3500, and high-multiplex (1800 fibers).
