=== NEO-discovery statistics === The table below lists the number of discoveries made by LONEOS each year of operation. Asteroids thought to be larger than one kilometer in diameter were used as benchmarks in assessing survey completeness. Hence, some table elements have two numbers separated by a slash. The second number represents the number of discoveries larger than one kilometer. The column labeled "Asteroid Observations" is the number of observations sent to the Minor Planet Center. Each asteroid was typically observed four times (once per frame) each night.<ref>[http://www.minorplanetcenter.org/iau/lists/YearlyBreakdown.html Summary of PHA and NEA Discoveries by Discoverers<!-- Bot generated title -->]</ref> {| class="wikitable" style="text-align: right; font-size: 0.9em; margin-left: 10px;" |- ! width=50 | Year !
