Counting Statistics and establishing the 1-count level
Know and use the statistical error information provided in the CDF files. The error associated with the inherent spectrometer counting statistics is provided in the CDF files for both the moments and for the distributions. The actual counts can be recovered from the distErr variable from C = (f/distErr)**2 with distErr from the dist CDFs.
Quasi-neutrality Check
Comparison of the FPI ion and electron density moments can give some indication as to how much of the underlying plasma distribution is represented in the separate FPI, HPCA, EIS, FEEPS data files.
