摘要：

This paper presents the 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 multiobject spectrograph (MOS) at the CFHT. A comparison of the photometry from the PDCS catalogs and from the new images we have obtained at the CFHT shows that the different magnitude systems can be cross-calibrated. After identification between the PDCS catalogs and our new images, we built catalogs with redshift, coordinates, and V-PDSC, I-PDSC, and R-COP magnitudes. We have classified the galaxies along the lines of sight into field and structure galaxies using a gap technique from Katgert ct al. In total we have observed 18 significant structures along the 10 lines of sight.
