Erratum: Brightening X-Ray Emission from GW170817/GRB 170817A: Further Evidence for an Outflow (Astrophysical Journal Letters (2018) 853 (L4) DOI: 10.3847/2041-8213/aaa4f3)

© 2018. The American Astronomical Society. We correct an error in Ruan et al. (2018), wherein the values for the X-ray photon index γ and the absorbed X-ray flux F0.38 keV are inadvertently switched for GW170817/GRB 170817A at 109.2 days post-merger. This typo appears in Table 1 and in the text of the published article. Below, we provide an updated version of Table 1 containing the correct values. The conclusions of the article are not affected. We thank Harvey Tananbaum for pointing out this error. (Table Presented).
