WIND Solar Wind Experiment, SWE, Faraday cup data: this data set contains three-dimensional measurements of ions in the energy range 150 eV to 8 keV. Placed 15° above and below equatorial plane of the spacecraft, the Faraday Cups measure ion charge flux as a function of epoch, cup number, orientation angle, and bias grid potential. For each time point, a full spectrum is comprised of charge flux measurements at the two Faraday cup sensors at 20 azimuth angles for each of 31 energy-per-charge windows with 1240 data points per spectrum. Spectra are built up over approximately 92 s intervals. The effective area of the Faraday cup sensor as a function of incidence angle onto the cup is also provided.

Epoch
Epoch Time Tags, default time at the beginning of the spectrum
The Epoch is defined as the number of milliseconds since 01-Jan-0000 00:00:00.000, as computed using the CDF library's internal date routines. Year zero i convention chosen by NSSDC to measure epoch values. This date is more commonly referred to a BC. Remember tha BC wa leap year. The CDF date/time calculations do not take into account the changes to the Gregorian calendar, and cannot be directly converted into Julian date/times. To convert CDF epochs into date/times and vice versa, you should only use the CDF_EPOCH routine with either the BREAKDOWN_EPOCH or CONVERT_EPOCH keywords. This Parameter exhibits an increasing Monotonic Progression.

The noise limit of this measurement is approximately 0.69 pA. Models of charge flow into the cup from oblique angles to the cup axis should account for projection of the aperture onto the collector. The calibrated effective area of the cup is given a function of incidence angle in the lookup table.
