Description

The TIDE H0 CDF files contain H+, O+, and He+ data below 411 eV. Data are available for 1996-03-27 through 1996-09-30. Data is accumulated over the 6-second Polar spacecraft spin. For each ion, the files contain moments density, velocity (Vx, Vy, Vz), temperature (T_perp and T_para) and spectogram for differential energy flux versus energy (flux averaged over spin and polar angle), differential energy flux versus spin angle (flux averaged over energy and polar angle), and differential energy flux versus polar angle (flux averaged over energy and spin angle). Support data includes EFI spacecraft potential (adjusted by +2 volts), magnetic field location, spacecraft ram direction, plotting information, and several parameters that describe the instrument status and details about the data processing.

Caveats
TIDE was originally designed to detect mass-resolved ions, H+, O+, He+, and NO+, for 32 energy steps (31 reported), 32 spin angle bins, and 7 polar angle channels. The detection of time-of-flight direct-events deteriorated rapidly early in the mission, reducing the ability to resolve ion masses and resulting in the lost of information in one axis (Z). After 09/30/96, the ion data is of poor quality and as a result, only Total Ions (Stops) are reported starting 12/08/96. Total Ions is the sum over the 7 polar angle channels of the particle counts detected by the Stop microchannel plate (MCP) detectors. The resolution in the 32 energy steps and in the 32 spin angle bins is retained. 1996 H+, O+, and He+ data are reported in the TIDE H0 CDFs. In order to avoid damage to the MCPs, starting 03/27/96 and continuing throughout the rest of the mission, the high voltage on the MCPs is reduced during radiation belt passes.

Spins Averaged
ParameterKey
spin_avg
Description

Spins Averaged: the number of spacecraft spins over which the data is averaged for each time period. For ISTP TIDE CDFs, no spin averaging is used, spin_avg=1.

Minimum count subtracted
ParameterKey
sub_min
Description

Minimum count subtracted. If sub_min = 1, the minimum count in each spin of data was subtracted as a means of reducing the noise level. If sub_min = 0, no minimum count subtraction was done.

spectrogram count option
ParameterKey
sum_avg
Description

Spectrogram count option: Three options for plotting counts in spectrograms. The counts plotted in the spectrograms can be the sum (1), the average (2), or the maximum (3) of the data whose ranges are specified in spect_lim. For the ISTP TIDE H1 and H0 CDFs, the counts are averaged.

Mask correction factor
ParameterKey
mask_corr
Description

Mask correction factor: A background mask, generated by averaging data with signal excluded, is subtracted from each six second set of data. Each Mask count is multiplied by the Correction factor in order to avoid over- or under-correction for the mask. In the the TIDE H1 and H0 CDF files, a correction of 0.8 is used.
