-    Operation Reinhard (1942–1943) was the largest single murder campaign of the
-    Holocaust, during which some 1.7 million Jews from German-occupied Poland were
-    murdered by the Nazis. Most perished in gas chambers at the death camps Belzec,
-    Sobibor, and Treblinka. However, the tempo, kill rates, and spatial dynamics of
-    these events were poorly documented. Using an unusual dataset originating from
-    railway transportation records, this study identifies an extreme phase of
-    hyperintense killing when >1.47 million Jews—more than 25% of the Jews killed
-    in all 6 years of World War II—were murdered by the Nazis in an intense,100-day
-    (~3-month) surge.  Operation Reinhard is shown to be an extreme event, based on
-    kill rate, number, and proportion (>99.9%) of the population murdered in camps,
-    highlighting its singularly violent character, even compared to other more
-    recent genocides. The Holocaust kill rate is some 10 times higher than
-    estimates suggested by authorities on comparative genocide.
