The PRIsm MUlti-object Survey (PRIMUS). II. Data Reduction and Redshift Fitting

Understand

The PRIsm MUti-object Survey (PRIMUS) is a spectroscopic galaxy redshift survey to z~1 completed with a low-dispersion prism and slitmasks allowing for simultaneous observations of ~2,500 objects over 0.18 square degrees.

• The final PRIMUS catalog includes ~130,000 robust redshifts over 9.1 sq.
• deg.
• In this paper, we summarize the PRIMUS observational strategy and present the data reduction details used to measure redshifts, redshift precision, and survey completeness.
