Excellent callout and my mistake missing the point on the wider energy range and the rollover. Thank you! The additional data will help the determination of dark matter vs. pulsars as the positron source.

"To determine if the observed new phenomenon is from dark matter or from astrophysical sources such as pulsars, AMS is now[sic] making measurements to determine the rate of decrease at which the positron fraction falls beyond the turning point (item 5), as well as to determine the antiproton fraction (the ratio of antiprotons to protons plus anti-protons). These will be reported in future publications."
