The echo intensity scale factor is about 0.45 dB per ADCP count. The Sentinel V ADCP does not directly
check for the validity of echo intensity data.

The Sentinel V ADCP always collects single ping data; therefore, raw data output from the Sentinel V
ADCP will not contain % good data. However, the average PD0 files created by Velocity will have % good
data. The percent-good data field is a data-quality indicator that reports the percentage (0 to 100) of good
data collected for each depth cell of the velocity profile. The setting of the Coordinate Transformation (de-
fault coordinate system is beam) determines how the Sentinel V references percent-good data as shown
below.

Note 1. Because profile data did not exceed correlation threshold.
Note 2. Because the error velocity threshold was exceeded.

Description
Stores correlation magnitude data for depth cell #1, beam #3. See above.
Stores correlation magnitude data for depth cell #1, beam #4. See above.
These fields store correlation magnitude data for depth cells 2 through maximum #
cells (depending on the ReadyV setting) for all four beams. These fields follow the
same format as listed above for depth cell 1.
Description
Stores the echo intensity data identification word (00 03h).
Stores echo intensity data for depth cell #1, beam #1. See above.
Stores echo intensity data for depth cell #1, beam #2. See above.
Stores echo intensity data for depth cell #1, beam #3. See above.
Stores echo intensity data for depth cell #1, beam #4. See above.
These fields store echo intensity data for depth cells 2 through maximum # of cells
(depending on the ReadyV Setting) for all four beams. These fields follow the same
format as listed above for depth cell 1.
