Best fit Orphan stream model in the presence of the LMC

<p>We give the best fit stream model and orbit for Orphan in the presence of the LMC from the work of Erkal et al. 2019 (<a href="https://ui.adsabs.harvard.edu/abs/2019MNRAS.487.2685E">https://ui.adsabs.harvard.edu/abs/2019MNRAS.487.2685E</a>). As described in section 4 of that work, this best fit was achieved in a prolate Milky Way halo which responds to the LMC. See the table in the appendix of that work (A1) for the parameters used in the fit.</p> <p>The file containing the orbit (orphan_orbit.txt) gives the position of the Orphan progenitor, LMC, and Milky Way for the past 5 Gyr. The coordinates are Galactocentric in a right-handed system (i..e the Sun is at (-8.1,0,0) kpc and predominantly moving in the positive y direction).&nbsp;</p> <p>The file containing the stream (orphan_stream.txt) gives the position of the Orphan stream particles in Galactocentric coordinates as well as observables (ra,dec,distance,vr,pmra,pmdec) assuming the Sun is at&nbsp;(-8.1,0,0) kpc and moving with a velocity of (11.1,245,7.3) km/s. The stream is generated using the Lagrange point stripping technique as described in the paper.&nbsp;</p> <p>Please cite Erkal et al. 2019 if you make use of this simulation.</p>
