  We present data from the Apache Point Observatory Lunar Laser-ranging
Operation (APOLLO) covering the 15-year span from April 2006 through the end of
2020. APOLLO measures the earth-moon separation by recording the round-trip
travel time of photons from the Apache Point Observatory to five
retro-reflector arrays on the moon. The APOLLO data set, combined with the
50-year archive of measurements from other lunar laser ranging (LLR) stations,
can be used to probe fundamental physics such as gravity and Lorentz symmetry,
as well as properties of the moon itself. We show that range measurements
performed by APOLLO since 2006 have a median nightly accuracy of 1.7 mm, which
is significantly better than other LLR stations.
