Corrected_MVBS
Corrected_MVBS is an analysis export variable available in exported integration analyses when the School Detection module is licensed.
It reports the value of Corrected_mean_amplitude in the dB domain (dB re 1m2/m3). This is a representation of the mean Sv of a school represented by a region on an echogram corrected for known beam geometry according to the system of Diner (1998).
MVBS is an acronym for Mean Volume Backscattering Strength (that is, mean Sv).
This variable is exported only if it is selected on the Export page of the EV File Properties dialog box.
