            Variables:

Epoch: TT2000 epoch, nanoseconds since 2000.

BuBu:  Bu Autocorrelation

BvBv:  Bv Autocorrelation

BwBw:  Bw Autocorrelation

EuEu:  Eu Autocorrelation

EvEv:  Ev Autocorrelation

EwEw:  Ew Autocorrelation

TotalPowerB: Virtual variable that sums the three B autocorrelations
TotalPowerE: Virtual variable that sums the two spin plane E autocorrelations (W axis is periocially corrupted by spacecraft shaddowing).

WFR_bins:  Number of bins in the original FFT spectra that are summed together on board to produce the current frequency bin.

WFR_bandwidth:  Bandwidth of each WFR bin.

WFR_frequencies: Center band frequency for each frequency bin.  Frequencies are logarithmically spaced.

LWEzGainW:  Attenuator select indicator for W axis.  0 – Off, 1 – On.   Switches in a 19 dB attenuator.   L2 and greater data has the attenuator gains folded into data to provide correct science units. 

LWExEyGainUV:  Attenuator select indicator for U and V axis.  0 – Off, 1 – On.   Switches in a 19 dB attenuator.  L2 and greater data has the attenuator gains folded into data to provide correct science units. 

SCMBW: EFW Bandwidth limiter select indicator for MSC.  0 – Off, 1 – On.   Switches in a 19 dB attenuator.  L2 and greater data has the attenuator gains folded into data to provide correct science units. 

SCMGain: Attenuator select indicator for MSC.  0 – Off, 1 – On.   Switches in a 19 dB attenuator.  L2 and greater data has the attenuator gains folded into data to provide correct science units.  

SPTT:  Sun Pulse time tag.   Epoch of the last sun pulse. 

APID:   Data APID
