Some experiments have also been conducted to understand the effect of initial starting location on the resulting drift velocity.
Results: Drift, defined as displacement from original head positioning at first data acquisition and before initiation of motion, was negligible (±0.8°).
By comparison with the results from a reference spraying, the resulting drift reduction potentials were compared with the results from three other drift assessment methods (field, wind tunnel, Phase Doppler particle analyser (PDPA) laser measurements).
For example, it is found that when ωτ decreases rapidly over the heliospheric polar regions, the resulting drift coefficient at 1 AU becomes smaller at the poles compared to its value in the equatorial plane.
Thus, a constant resulting drift velocity is the consequence depending on size and shape of analyte ions.
LW carried out the experimental work and collection of data, analysis and interpretation of results, drifting and substantial editing the manuscript.
TK was responsible for conception and participation in design, experimental work and collection of data, analysis and interpretation of results, drifting and substantial editing the manuscript.
YLY, LD and YYD was responsible for conception and participation in design, experimental work and collection of data, analysis and interpretation of results, drifting and substantial editing the manuscript.
Some SNPs may be associated with this classification as a result of drift in each cycle, but it would be unlikely that the same SNPs would be subject to drift in different cycles and in the two different populations.
It seems a consequence of the Brand/Ross scandal but one wonders whether it was intentional or a result of drift.
