Description
H+, O+, He+ and He++ upflowing fluxes and statistical uncertainties processed by the TIMAS science team.These data were used in preparing several papers, see Information URLs. Includes also non-TIMAS Data: UT, altitude, invariant latitude, L shell, magnetic local time, geomagnetic latitude (signed - n/s hemisphere), average magnetic field vector in GSM coordinates at Polar (uses KH's co-ord conversion code), spacecraft potential from EFI data base, solar zenith angles at each end of the field line, time delayed solar wind parameters from WIND (Using KH's database) interpolated across data gaps of less than 10 minutes, IMF in GSM, solar wind dynamic pressure (nPa), solar wind density (/cc), solar wind velocity (km/sec). This is a summary data base.It does not contain detailed energy step and pitch angle information for each data point. Extends over all altitudes, invariant latitudes and MLT. Below altitude of 4.0 Re 2 spin resolution (12s), above altitude of 4.0 Re 4 spin resolution (24s). Reference:E.G. Shelley et al., The Toroidal Imaging Mass-Angle Spectrograph (TIMAS) for the Polar Mission, Sp. Sci. Rev, Vol 71, pp 497-530, 1995.

Caveats
Several compromises were made in assembling the data base. In particular background subtraction, short averaging intervals and the normally low count rates for minor ions (O+, He+, and He++) lead to many data intervals where the data values reported are not statistically significant. The data files therefore contain many diagnostic parameters and data quality flags.

Name
FEC counts
ParameterKey
Fec
Description
Average counts per spin in the fast event counter
Caveats
The TIMAS detector has a non linear response at high count rates that is, to some extent corrected for in the software that generated the data here. The correction, however introduces some uncertainty. The FEC count rate is carried as an indication of the corrections applied to the raw data.
