Modeling deviations from GR, their equation 1 gives the metric they&amp;#x27;ve decided to use for this paper. This equation contains 2 &amp;quot;Newtonian potentials describing temporal and spatial perturbations to the metric.&amp;quot; In other words, the paper is about testing Newtonian parameters. They refer to this paper as the source of their equation 1: Cosmological Perturbation Theory in the Synchronous and Conformal Newtonian Gauges by Ma and Bertschinger. http://arxiv.org/abs/astro-ph/9506072 Again, it&amp;#x27;s about Newtonian parameters.&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/astro-ph_9506072/"&gt;Paper and discussion history&lt;/a&gt;.
