The density of uniformly distributed sources of equal intrinsic intensity was found to be larger than similar to (0.06 -- 5) x 10(-4) Mpc(-3) at 95{\%} CL, depending on the magnitude of the magnetic defections. Similar bounds, in the range (0.2 -- 7) x 10(-4) Mpc(-3), were obtained for sources following the local matter distribution.", optnote="WOS:000320161400011", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1497), last updated on Mon, 26 Aug 2013 11:54:58 +0000", issn="1475-7516", doi="10.1088/1475-7516/2013/05/009", opturl="http://arxiv.org/abs/arXiv:1305.1576", opturl="https://doi.org/10.1088/1475-7516/2013/05/009", archivePrefix="arXiv", eprint="arXiv:1305.1576", language="English" }
