    "abstract": "A test of Lorentz invariance for electromagnetic waves was performed by\ncomparing the resonance frequencies of two stable optical resonators as a\nfunction of orientation in space. The crystalline resonators were operated at\n3.4 K in a cryostat employing a pulse-tube refrigerator. A new analysis yields\nthe Robertson-Mansouri-Sexl theory parameter combination\n$\\beta-\\delta-1/2=(-0.6\\pm 2.1\\pm1.2)\\cdot10^{-10}$ and one parameter of the\nStandard Model Extension theory, $(\\tilde{\\kappa}_{e-})^{ZZ} =\n(-2.9\\pm2.2)\\cdot 10^{-14}$.",
