This part, "zCOSMOS-bright", was designed to yield a high and fairly uniform sampling rate (about 70%), with a high success rate in measuring redshifts (approaching 100% at 0.5 < z < 0.8), and with sufficient velocity accuracy (about 100 km/s) to efficiently map the environments of galaxies down to the scale of galaxy groups out to redshifts z ~ 1.2008Msngr.134...35Lhttps://dc.g-vo.org/zcosmos/q/ssa/infoSurveyIsServedByGAVO Data Center ObscoreGAVO Data Center TAP servicehttp://dc.g-vo.org/zcosmos/q/ssa/ssap.xml?https://dc.g-vo.org/zcosmos/q/ssa/ssap.xml?GETapplication/x-votable+xmlPOSICRS position of target objectdegcharSIZESize of the region of interest around POSdegrealBANDWavelength (range) of interest (or symbolic bandpass names)mcharTIMEMidpoint of exposure (MJD)time.epochcharFORMATMIME type of the file servedmeta.code.mimecharAPERTUREAngular diameter of aperturedegphys.angSize;instr.fovcharSNRSignal-to-noise ratio estimated for this datasetstat.snrcharREDSHIFTRedshift of target objectsrc.redshiftcharTARGETNAMECommon name of object observed.meta.id;srccharTARGETCLASSObject class (star, QSO,...; use Simbad object classification http://simbad.u-strasbg.fr/simbad/sim-display?data=otypes if at all possible)src.classcharMTIMEDate last published.charFLUXCALIBType of flux calibration (ABSOLUTE, CALIBRATED, RELATIVE, NORMALIZED, or UNCALIBRATED).charSPATRESSpatial resolution of datadegpos.angResolutioncharWAVECALIBType of wavelength calibrationmeta.code.qualcharCOLLECTIONA short handle naming the collection this spectrum belongs to.charSPECRPLower limit to spectral resolution power (λ/Δλ) as a single number.realPUBDIDDataset identifier assigned by the publishermeta.ref.ivoidcharCREATORDIDDataset identifier assigned by the creatormeta.idcharWILDTARGETShell pattern of target observed (case insensitive)charWILDTARGETCASEShell pattern of target observed (case sensitive)charREQUESTThis is queryData for the default operation; some services support getData as wellcharTOPOnly return the TOP "best" records (on this service, this usually is equivalent to MAXREC, so no ranking is implied).integerCOMPRESSReturn compressed results?charRUNIDAn identifier for a certain run.
