The Heidelberg InfraRed Optical Cluster Survey (HIROCS). I. Layout, instrumentation, and data analysis. Roeser H.-J., Hippelein H., Wolf C., Zatloukal M., Falter S. <Astron. Astrophys., 513, A15-15 (2010)> =2010A&A...513A..15R
ADC_Keywords: Surveys ; Clusters, galaxy ; Redshifts Keywords: galaxies: clusters: general - surveys - methods: data analysis Abstract: We describe a survey for distant clusters of galaxies that identified clusters as local overdensities in the 3D galaxy distribution. Optical and near-IR imaging in B, R, i, z, and H are used to derive photometric redshifts for objects as faint as m*+1 at a redshift of 1.5. We outline the astrometric and photometric data reduction. The 3D cluster search, based on the photometric redshifts, is described. Description: Optical data in B, R, i, and z were collected with LAICA at the prime-focus of the Calar Alto 3.5 m-telescope. In addition, we used the Wide-Field-Imager (WFI) at the 2.2 m-telescope on La Silla during MPG-time to obtain B and R images. Observations started in July 2002 with LAICA, in December 2002 with WFI, and in September 2003 with OMEGA2000. By August 2008, data collection was complete. File Summary:

Note (1): Table made of 3 parts: * The first part of the table lists those candidates (78) which have six or more member galaxies for the restricted photometric redshift errors. * The second part gives those candidates (32) who fall below the limit of 6 members in the restricted sample. * The third section gives those candidates (4) who do not have any member galaxy with a photometric redshift error less than 0.15. Note (2): The gnomonic positions X and Y refer to the pointing centre of (J2000) 03:06:12.48-00:20:38.
