Our deep, wide-field $g,i$ photometry reaches $\\sim$3 magnitudes fainter than the photometry in the Pan-STARRS1 discovery paper and allows us to trace the stellar population of Lac I beyond two half-light radii from the galaxy center. We measure a Tip of the Red Giant Branch (TRGB) distance for Lac I of $(m-M)_0=24.44\\pm0.11$ mag (773$\\pm$40 kpc, or 264$\\pm$6 kpc from M31), which is consistent with the Pan-STARRS1 dist","authors_text":"David J.
