Million Quasars v2.5 -- fixing early quasar positions
The MILLIQUAS (Million Quasars) catalogue v2.5 is now available for
download. For this edition, I've investigated hundreds of early (1970's-1980's) quasars which were originally published with approximate co-ordinates (typical of those days), and have moved ~200 to their correct optical source. Thus an original name often replaces a recent SDSS name, because original names are always used. Authors from those days (or any day) are invited to check that their objects are correctly positioned, and to advise me of any corrections at . The catalogue & ReadMe are at http://quasars.org/milliquas.htm , and also can be queried on the NASA HEASARC site http://heasarc.gsfc.nasa.gov/W3Brows...milliquas.html Eric Flesch Wellington, New Zealand |
