The second international celestial reference frame (icrf2)... Derived using data from August 1979 through March 2009, it is a great improvement over the original ICRF with 3414 extragalactic radio source positions, a noise floor of 40 microarcsec, and axis stability of 10 microarcsec....
The study of radio flux density variations of the quasar oj 287 by the wavelet and the singular spectrum methodsFlux density variations of the extragalactic radio source OJ 287 are studied by applying the wavelet and the singular spectrum methods to the long-term monitoring data at 14.5,...
