The PRIsm MUlti-object Survey (PRIMUS). II. Data Reduction and Redshift
  Fitting
  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. The survey motivation, observational techniques, fields, target
selection, slitmask design, and observations are presented in Coil et al 2010.
Comparisons to existing higher-resolution spectroscopic measurements show a
typical precision of sigma_z/(1+z)=0.005. PRIMUS, both in area and number of
redshifts, is the largest faint galaxy redshift survey completed to date and is
allowing for precise measurements of the relationship between AGNs and their
hosts, the effects of environment on galaxy evolution, and the build up of
galactic systems over the latter half of cosmic history.
