Data Output Format:

  Header Line:

  NNNNN YY MM DD HH MM SS HHH.HH PPP.PP RRR.RR DDD.DD TTT.TT FFF.FF SS.SS

    where NNNNN    = Ensemble number
          YY MM DD = Date
          HH MM SS = Time
          HHH.HH   = Heading, deg
          PPP.PP   = Pitch, deg
          RRR.RR   = Roll, deg
          DDD.DD   = Depth, m
          TTT.TT   = Temperature, C
          FFF.FF   = Distance to middle of first bin, m
          SS.SS    = Bin size, m

  Followed by Data Lines for each Bin:

  NNN XXXX.X YYYY.Y ZZZZ.Z RRRR.R CCC EEE GGG

    where NNN    = Bin number (ordered highest to lowest)
          XXXX.X   X velocity (relative to instrument), cm/s
                   + is along-channel flow into Lake Michigan
                   - is along-channel flow into Muskegon Lake
          YYYY.Y = Y velocity (relative to instrument), cm/s
                   + is cross-channel flow to the North
                   - is cross-channel flow to the South
          ZZZZ.Z = Z velocity (relative to instrument), cm/s (N/A)
          RRRR.R = Error velocity, cm/s
          CCC    = Average correlation for all beams (0-255)
          EEE    = Average echo intensity for all beams (0-255)
          GGG    = Four beam percent good (0-100)

    note: Values of 999.9 represent invalid velocity values
          Values of 999   represent missing correlation, echo
                          intensity, or percent good values
