ARXA and Milliquas catalogs available on-line

The Atlas of Radio/X-ray Associations (ARXA) has been in submission
for the past two months, but no reply yet from the referee. This
catalog has 602,570 optical objects with X-ray associations listed
from Chandra, XMM-Newton, ROSAT RASS, HRI, PSPC and WGA, and radio
associations from NVSS, FIRST, and SUMSS. Also, existing
identifications with redshifts are displayed. It is the successor to
the QORG (2004,A&A,427,387 ) catalog. I am tempted to place this on
arXiv, but prefer to get the review done first.

The catalog, ReadMe, and sample data for quick browsing are on
http://quasars.org/arxa.htm

There is also a quasar catalog available, it is not in submission for
now, maybe later. It has 1,101,872 objects which, using their
expectation values, will yield 1,013,360 actual quasars. Each object
is shown with an associated radio/X-ray detection where applicable.
This catalogue, ReadMe and sample data are available from
http://quasars.org/milliquas.htm
