The Canada-France-Hawaii telescope optical PDCS survey (COP). I. The data

This paper presents the COP (CFHT optical PDCS; CFHT: Canada-France-Hawaii Telescope, PDCS: Palomar Distant Cluster Survey) survey data. We describe o ur photometric and spectroscopic observations with the multiobject spectrog raph (MOS) at the CFHT. A comparison of the photometry from the PDCS catalo gs and from the new images we have obtained at the CFHT shows that the diff erent magnitude systems can be cross-calibrated. After identification betwe en the PDCS catalogs and our new images, we built catalogs with redshift, c oordinates, and V-PDSC, I-PDSC, and R-COP magnitudes. We have classified th e 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 significa nt structures along the 10 lines of sight.
