The Million Optical - Radio/X-ray Associations (MORX) catalog

(2016, PASA, 33, 52) 


The MORX (Million Optical radio/X-ray Associations) catalog presents 1,002,855 optical objects which are calculated as being 40%-100% likely to be associated to radio or X-ray sources, as at July 2016.  Astrometry, photometry, classifications, and identifications of the radio/X-ray sources are included, full details are in the pre-print paper and ReadMe.  There is also a 118,200-object supplementary file of anonymous SDSS galaxies with radio/X-ray associations -- those SDSS data were not to hand in time for inclusion in the main catalog.    

Quick browse of (flat text) data here , and here is the ReadMe.  Pre-print paper is here.

Four files are available: (1) the main MORX data file, (2) the supplemental file, (3) the ReadMe, and (4) the references (citations) file.
