Pickup Ions – Time Series
Correlation of counts with the solar
velocity caused by two effect:
1. Efficiency:
-Varying solar wind velocity over
time, which causes a varying
detection efficiency
2. Instrumental cut-off:
- PUIs can be detected in a
range of
EThresh – Emax
which causes a different
coverage of velocity spectra for
different species.
