  The Apache Point Lunar Laser-ranging Operation (APOLLO) has been collecting
lunar range measurements for 15 years at millimeter accuracy. The median
nightly range uncertainty since 2006 is 1.7 mm. A recently added Absolute
Calibration System (ACS), providing an independent assessment of APOLLO system
accuracy and the capability to correct lunar range data, revealed a 0.4%
systematic error in the calibration of one piece of hardware that has been
present for the entire history of APOLLO. Application of ACS-based timing
corrections suggests systematic errors are reduced to < 1 mm, such that overall
data accuracy and precision are both 1 mm. This paper describes the processing
of APOLLO/ACS data that converts photon-by-photon range measurements into the
aggregated normal points that are used for physics analyses. Additionally we
present methodologies to estimate timing corrections for range data lacking
contemporaneous ACS photons, including range data collected prior to
installation of the ACS. We also provide access to the full 15-year archive of
APOLLO normal points (2006-04-06 to 2020-12-27).
