标题： The CFH Optical PDCS survey (COP) I: The Data

摘要： 本文介绍了COP（COP: CFHT光学PDCS；CFHT: 加拿大-法国-夏威夷望远镜；PDCS: Palomar遥远星团巡天）巡天数据。我们描述了使用CFH望远镜上的MOS多狭缝光谱仪进行的测光和光谱观测。将PDCS（Postman等，1996年）目录中的测光数据与我们在CFH望远镜上获得的新图像进行比较表明，不同的星等系统可以相互校准。在PDCS目录与我们的新图像之间完成识别后，我们构建了包含红移、坐标以及V、I和R星等的目录。我们使用间隙技术（Katgert等，1996年）沿视线方向将星系分类为场星系和结构星系。总共我们沿10条视线观测到了18个显著的结构。 显示英文摘要

摘要： This paper presents and gives the COP (COP: CFHT Optical PDCS; CFHT: Canada-France-Hawaii Telescope; PDCS: Palomar Distant Cluster Survey) survey data. We describe our photometric and spectroscopic observations with the MOS multi-slit spectrograph at the CFH telescope. A comparison of the photometry from the PDCS (Postman et al. 1996) catalogs and from the new images we have obtained at the CFH telescope shows that the different magnitude systems can be cross-calibrated. After identification between the PDCS catalogues and our new images, we built catalogues with redshift, coordinates and V, I and Rmagnitudes. We have classified the galaxies along the lines of sight into field and structure galaxies using a gap technique (Katgert et al. 1996). In total we have observed 18 significant structures along the 10 lines of sight.
