This analysis draws on the sample of ~44000 RR Lyrae (RRab) stars from the Pan-STARRS1 (PS1) 3{pi} survey, which is ~80% complete and ~90% pure within 80 kpc, and extends to >~120kpc with a distance precision of ~3% . A projection of RR Lyrae stars within |^~^B|_{sun}_<9{deg} of the Sgr stream's orbital plane reveals the morphology of both the leading and the trailing arms at very high contrast across much of the sky. In particular, the map traces the stream near- contiguously through the distant apocenters. We fit a simple model for the mean distance and line-of-sight depth of the Sgr stream as a function of the orbital plane angle ^~^{Lambda}_{sun}_, along with a power-law background model for the field stars. This modeling results in estimates of the mean stream distance precise to ~1% and it resolves the stream's line-of-sight depth. These improved geometric constraints can serve as new constraints for dynamical stream models. 2017ApJ...850...96H https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/850/96 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/337 : Gaia DR1 (Gaia Collaboration, 2016) II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016) J/AJ/127/2031 : Catalog of neighboring galaxies (Karachentsev+, 2004) J/AJ/127/1158 : QUEST RR Lyrae Survey first catalog (Vivas+, 2004) J/AJ/136/1645 : Spectroscopy of bright QUEST RR Lyrae stars (Vivas+, 2008) J/ApJ/731/119 : BHB candidates in Sagittarius stream (Ruhland+, 2011) J/ApJ/750/99 : The Pan-STARRS1 photometric system (Tonry+, 2012) J/ApJ/765/154 : RR Lyrae stars in the Catalina Sky Survey (Drake+, 2013) J/AJ/146/21 : LINEAR.
