The DEEP survey is a two-phased project using the Keck telescopes to study the distant Universe.
- Phase 1 used the LRIS spectrograph to study a sample of ~1000 galaxies to a limit of I=24.5.
- Phase 2 of the DEEP project is using the new DEIMOS spectrograph to obtain spectra of ~50,000 faint galaxies with redshifts z > 0.7.
- Instrument DEIMOS spectrograph on Keck II
- Principal Redshift Range 0.75 < z < 1.4, preselected using BRI photometry
- Four, each 120' by 30'
