Target_depth_min is an analysis export variable.
It reports the minimum depth of all the single targets within the domain which was analyzed (m).
This variable is exported only if it is selected on the Export page of the EV File Properties dialog box.
Warning: This is calculated using Target_depth not Target_true_depth. This is of particular relevance to data collected from a horizontally oriented transducer.
