Query: Improved Spectral Representations of Neutron-Star Equations of State   Spectral representations have been shown to provide an efficient way to
represent the poorly understood high-density portion of the neutron-star
equation of state. This paper shows how the efficiency and accuracy of those
representations can be improved by a very simple change.
