Led by astronomers at the Center for Astrophysics Harvard & Smithsonian, 2MRS used data collected from … WebThe first systematic redshift survey was the CfA Redshift Survey of around 2,200 galaxies, started in 1977 with the initial data collection completed in 1982. This was later extended to the CfA2 redshift survey of 15,000 galaxies, [5] completed in the early 1990s.

WebThe Optical Redshift Survey (Santiago et al., 1995), had a depth of 80h-1 Mpc, similar to the first CfA survey, but attempted a complete coverage of the sky (except for the dusty avoidance zone around the galactic equator). They measured about 1300 new redshifts, including about 8500 redshifts in total.
