Abstract

The precise determination of moving cluster parallaxes plays an important role in the calibration of cosmic distance scale as well as many other astrophysical relations. Various models and improvements on determination of moving cluster parallax have been made in the last century. This paper gives a brief review on the progress of moving cluster parallax determination, including some work done by the authors.
