Over the past several decades, dozens of tests have sought the 132 Lorentz-violating degrees of freedom in the nonrelativistic limit of the minimal matter sector of the standard-model extension, yet 43 remained unconstrained. In this Letter, we limit all previously unconstrained degrees of freedom and make improvements on 13 prior limits. The approach introduced here offers the potential of further improvements for 49 degrees of freedom in suitable future experiments, along with additional discovery potential offered by combining data from experiments performed in different locations.
