  1. Abbreviations are as follows: semi-major and -minor axes of the projected ellipse (\(a{\prime}\), and \(b{\prime}\)), position angle of the semi-minor axis of the ellipse (\(\theta\)), the offsets in the East-West and North-South directions between the predicted and the reconstructed positions of Hi’iaka's center (\(f\) and \(g\), respectively), the instantaneous and rotationally-averaged volume-equivalent diameter (\(D{\prime}\), and \(D\)), and the geometric albedo (\({p}_{V}\)).
