ADCP and Boogie Dopp profile data are documented on the second
sheet (velocity profiles) of these xl files

The first block of data contains BD data from the down beam.  In addition
to obvious data Within the 13 lines of header also listed are the velocity
scale (a calibration multiplier used by the processing software to correct
speed data (this is often 1.0).  Other parameters listed are vN (the vertical
profile number, the mean depth, in meters, vTime, the number of seconds from
the proceeding midnight, and v#GdCells, the number of good depth cells
determined by the unit based on depth, backscatter, and side lobe assumptions.

The block of data containing downward beam information includes:
Column 1 is the bin or cell number
Column 2 is depth below surface in meters
Column 3 is depth below surface in centimeters
Column 4 is uncorrected (for calibration) speed in meters per second
Column 5 is the calibration corrected speed in centimeters per second
Column 6 is distance above bed in centimeters
The value in blue at top of col. 6 is water depth in centimeters

The information in columns 4, 5, and 6 then repeat for all 20-21 profiles

Similar information is then shown in the 2nd block of data for the forward
BD acoustic beam. 

The third block of data contains three columns that include:
Column 1 is the bin or cell number
Column 2 is the depth below surface for the standard down (stdD) beam in meters
Column 3 is the depth below surface for the forward beam in meters

The 4th block of data is profile information for the ADCP measurements.
Information following four lines of header includes
Column 1 is distance below surface for each bin in meters
Column 2 is distance below surface for each bin in centimeters
Column 3 is speed in centimeters per second
Column 4 is distance above bed in centimeters for each profile listed
1st line of header is water depth measured by ADCP
4th line of header shows depth measured by BoogieDopp (in cm)

Column3 and 4 then repeat for all 20-21 measured profiles.

The third sheet in the xl file contains the BD output from the handheld computer
computer converted to ascii.  That information is similar to the BD
data on the second page (Velocity Profile)
