加拿大观测宇宙学网络（英语：Canadian Network for Observational Cosmology）（hocC2）场星系红移巡天是对天空中超过1.5度2的微弱星系进行的光谱/光度巡天，标称光谱极限为RC 21.5等。调查区域包括天空中四个相距甚远的斑块，总样本超过6000个红移，代表约45%的采样率。此外，还可以对大约40，000个星系的完整样本进行五色测光（IC，RC，V，B和U），RC为23.0等。我们描述了用于创建光谱光度目录的调查和观测策略、多物体光谱掩模设计程序以及数据简化技术。我们还讨论了统计权重的推导，包括有限的光谱带宽的影响，红移的样品，这使得它可以被用作一个完整的样本的校正。作为调查数据的初步发布，我们提供了补丁hocC 0223 + 00的完整数据集和一些统计数据。
The Canadian Network for Observational Cosmology (CNOC2) Field Galaxy Redshift Survey is a spectroscopic/photometric survey of faint galaxies over 1.5 deg2 of sky with a nominal spectroscopic limit of RC ∼ 21.5 mag. The primary goals of the survey are to investigate the evolution of galaxy clustering and galaxy populations over the redshift range of ∼0.1-0.6. The survey area contains four widely separated patches on the sky with a total sample of over 6000 redshifts, representing a sampling rate of about 45%. In addition, five-color photometry (in IC, RC, V, B, and U) for a complete sample of approximately 40,000 galaxies to RC ∼ 23.0 mag is also available. We describe the survey and observational strategies, multiobject spectroscopy mask design procedure, and data reduction techniques for creating the spectroscopic-photometric catalogs. We also discuss the derivations of statistical weights, including corrections for the effects of limited spectral bandwidth, for the redshift sample, which allow it to be used as a complete sample. As the initial release of the survey data, we present the full data set and some statistics for the patch CNOC 0223+00.
