MAG/MPL/M1 - Loss of transmit signal triggers incorrect height

Range gate information is incorrect because zero-height bin not identified due to 
insufficient transmit signal

null

• Height(height)
• Attenuated backscatter, co-pol(signal_return_co_pol)
• Quality check results on field: Attenuated backscatter, copol(qc_signal_return_co_pol)
• -180.0 - +180.0(alt)
• Bin number of first data. Tells where pretrigger timing ends and end of region
  for background data sampling laser_fire_bin(first_data_bin)
• Quality check results on field: Attenuated backscatter, cross pol(qc_signal_return_cross_pol)
• Subtract from range_bins to yield range(range_offset)
• Attenuated backscatter, cross pol(signal_return_cross_pol)
• Distance to the center of the corresponding range bin(range)
