6C** sample of steep-spectrum radio sources
Listed in IVOA Registry (Virtual Observatory)
We present basic observational data on the 6C** sample.
Description
This is a new sample of radio sources drawn from the 151-MHz 6C survey, which was filtered with radio criteria chosen to optimize the chances of finding radio galaxies at z>4. The filtering criteria are a steep-spectral index and a small angular size.
The final sample consists of 68 sources from a region of sky covering 0.421sr. We present Very Large Array radio maps, and the results of K-band imaging and optical spectroscopy.
