Johannsen-Psaltis metric

(JP metric)
(metric template allowing metrics to be written as a general expansion)

A Johannsen-Psaltis metric (JP metric) is a metric applicable to modifications to general relativity (GR). It includes an expansion term that is general enough that it can be customized to be "plain GR" or many of the proposed modifications. Thus, it can provide a framework for comparison, including comparison of theory with observation. A spacetime with such a metric is termed a Johannsen-Psaltis spacetime (JP spacetime).
