| Abstract: | Measurement of the observed anti-correlation between the field-perpendicular component of F-region plasma velocity in the north-south plane and the downward, field-parallel component has been proposed as a way to determine the value of the O-O+ collision frequency. However, random noise errors in measurements of plasma velocity made at EISCAT may combine in analysis to induce a spurious anti-correlation between the derived values of these components which is hard to distinguish from any genuine anti-correlation. |
