From Reference Frames to Relativistic Experiments : Absolute and Relative Radio

  title={From Reference Frames to Relativistic Experiments : Absolute and Relative Radio},
  author={Edward B. Fomalont},
Reference systems and frames are crucial for high precision absolute astrometric work, and their foundations must be well-defined. The current frame, the International Celestial Reference Frame, will be discussed: its history, the use of the group delay as the measured quantity, the positional accuracy of 0.3 mas, and possible future improvements. On the other hand, for the determination of the motion of celestial objects, accuracies approaching 0.01 mas can be obtained by measuring the… CONTINUE READING
