The Ne variable contains a measure of the plasma density computed by
neural networks. This value should always be considered WITH the
E_AVERAGE information since it should track the plasma line visible on
the dynamic spectrum. Sometimes, however, the neural network value will
be unreliable and this is especially true when in proximity to the
earth. Visual confirmation will indicate the presence of outliers, or
regions where the network is fallible. The parameter Ne_quality may
give some estimate of the reliability of the plasma density - but should
be used in conjunction with visual inspection.
