Abstract:
The PRIsm MUlti-object Survey (PRIMUS) is a spectroscopic galaxyredshift survey to z ~ 1 completed with a low-dispersion prism andslitmasks allowing for simultaneous observations of ~2500 objects over0.18 deg
2. The final PRIMUS catalog includes ~130,000 robustredshifts over 9.1 deg
2. In this paper, we summarize thePRIMUS observational strategy and present the data reduction detailsused to measure redshifts, redshift precision, and survey completeness.The survey motivation, observational techniques, fields, targetselection, slitmask design, and observations are presented in Coil etal. Comparisons to existing higher-resolution spectroscopic measurementsshow a typical precision of σ
z /(1 + z) = 0.005.PRIMUS, both in area and number of redshifts, is the largest faintgalaxy redshift survey completed to date and is allowing for precisemeasurements of the relationship between active galactic nuclei andtheir hosts, the effects of environment on galaxy evolution, and thebuild up of galactic systems over the latter half of cosmic history.
