Abstract:
This automated catalogue combines all the largest published optical,
radio and X-ray sky catalogues to find probable radio/X-ray
associations to optical objects, plus double radio lobes, using
uniform processing against all input data. The total count is 1002855
optical objects so presented. Each object is displayed with J2000
astrometry, optical and radio/X-ray identifiers, red and blue
photometry, and calculated probabilities and optical field solutions
of the associations. This is the third and final edition of this
method.
Description:
This is a compendium of optical objects which are calculated as
associated to XMM-Newton, ROSAT, Chandra or Swift X-ray sources, or to
NVSS, FIRST or SUMSS radio sources or double radio lobes. The counts
are:
Optical objects - 1,002,855
NVSS - 402,485 core radio associations, plus 8320 double radio lobes.
FIRST - 250,072 core radio associations, plus 16,934 double radio lobes.
SUMSS - 70,863 core radio associations, plus 2124 double radio lobes.
XMM-Newton - 184,203 X-ray associations
XMM Slew - 10,104 X-ray associations
ROSAT - 120,181 X-ray associations
Chandra - 91,674 X-ray associations
Swift - 47,200 X-ray associations
Each optical object is shown as one line bearing the J2000
coordinates, object name if any, object class, red & blue photometry,
redshift if any, likelihoods of the presented associations and
calculated odds that the object is a quasar, galaxy, star, or
erroneous association, and the radio & X-ray identifiers. Also,
details of positional offsets and optical field solutions are given,
plus references for the object name, redshift and classification.
A supplemental file ("morxsupp.dat") of 118,200 anonymous SDSS
galaxies with radio/X-ray associations has been added to the MORX
files. Those SDSS data came to hand just as MORX was in press, so are
included as this supplement. The file format is the same as MORX, and
their combined count is 1,121,055 optical objects. If citing, just
cite as MORX.
