Parallax astronomy
WebBy measuring the amount of displacement – the parallax angle – and knowing the distance between the Sun and the Earth, astronomers can determine the star’s distance using … WebJan 22, 2013 · The parallax factor (a dimensionless ratio) is indicated by the distance of the data point from the reference point (0, 0). The red and blue dots refer to positive and negative parallax factors, respectively. The correction to the parallax is determined by the correlation between the weighted residuals and the parallax factors.
