Data sets for all 11 stellar halo models at: http://www.astro.columbia.edu/~kvj/halos/ Files - halo??.dat: ======== Each file is an ascii list of all particles that have light associated with them, columns: nsat, x, y, z, vx, vy, vz, tub, pint, pext, age, fe/h, alpha/fe, mass - nsat gives satellites number from which particle came - positions in kpc (relative to Milky-Way-type parent) - velocities in km/s - tub = time at which particle became unbound from sat for first time (=0 if still bound) - pint = potential energy due to satellite particles in (km/s)^2 - ptot = total potential energy - age of stars in Gyrs - stellar mass associated with particle in msun If you do end up using these versions in pubs, please quote Bullock & Johnston (2005) and also Robertson et al (2005) and Font et al (2006) (also on the WWW site)
