PRISM多目标调查（PRIMUS）。II。数据约简与红移拟合
The PRIsm MUlti-object Survey (PRIMUS). II. Data Reduction and Redshift Fitting
摘要：
PRISm多天体巡天（PRIMUS）是一个光谱学星系红移巡天，以z~1完成，使用低色散棱镜和狭缝掩模，可以同时观测0.18平方度的约2，500个天体。最终的PRIMUS目录包括约130，000个超过9.1平方英尺的鲁棒红移。°的在本文中，我们总结了PRIMUS的观测策略，并提出了用于测量红移，红移精度和调查的完整性的数据减少的细节。Coil等人（2010年）介绍了调查动机、观察技术、视野、目标选择、狭缝掩模设计和观察结果。与现有的更高分辨率光谱测量的比较显示出sigma_z/（1+z）=0.005的典型精度。PRIMUS是迄今为止完成的最大的暗星系红移调查，可以精确测量AGN与其宿主之间的关系，环境对星系演化的影响，以及宇宙历史后半期星系系统的建立。
英文摘要：
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.
