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

fftSize: variable for the virtual varialbe to apply fft.  Default value is 16384

BwSpec: Virtual Variable to fft the BwSamples data at 16384 points.  This is handled automatically in Autoplot to produce spectrograms of the waveform data.

EuSpec: Virtual Variable to fft the EuSamples data at 16384 points.  This is handled automatically in Autoplot to produce spectrograms of the waveform data.

EvSpec: Virtual Variable to fft the EvSamples data at 16384 points.  This is handled automatically in Autoplot to produce spectrograms of the waveform data.

EwSpec: Virtual Variable to fft the EwSamples data at 16384 points.  This is handled automatically in Autoplot to produce spectrograms of the waveform data.
