This service will return recorded redshifts for a given object. http://nedwww.ipac.caltech.edu/help/data_help.html#zdat BasicData Research http://nedwww.ipac.caltech.edu/cgi-bin/nph-datasearch?search_type=Redshifts& GET application/xml+votable objname Name of object string of Output format parameter, must be "xml_main" for VOTable output. string Radio Millimeter Infrared Optical UV EUV X-ray Gamma-ray default default No. A sequential data-point number applicable to this list only. meta.number int Name in Publication The object's name in NED's standard format, of the object to which the data apply. meta.id;name string Published Velocity The radial velocity , derived from derived from the shift of some spectral feature, in km/sec km/sec src.spect.dopplerVeloc int
