Correlation Magnitude, Echo Intensity, Percent-Good, and Status Data Format

The number of depth cells is set by the
Correlation magnitude data give the magnitude of the normalized echo autocorrelation at the lag used for
estimating the Doppler phase change. The H-ADCP represents this magnitude by a linear scale between 0
and 255, where 255 is perfect correlation (i.e., a solid target). A value of zero indicates bad correlation val-
ues.
