Data collected by Taylor and Joel M. Weisberg and their colleagues of the orbital period of PSR B1913 +16 supported this relativistic prediction ; they reported in 1982 and subsequently that there was a difference in the observed minimum separation of the two pulsars compared to that expected if the orbital separation had remained constant .
