The astrometry files hold every SPHEREx detection with the spacecraft's position. They are drafts for planning, not Minor Planet Center submissions: the station code is a placeholder (XXX). The ephemeris is approximate: it comes from a preliminary orbit fitted to the measured motion, with its 1σ uncertainty on every row.
