Heave_min is an analysis export variable.

It reports the value for Heave_min of an interval in the analysis domain. Heave_min is the minimum heave value rounded to the nearest sample height. Heave_min is exported in depth mode only. Heave is accounted for in Sv echograms (in depth mode) when a Heave source line is selected on the Platform Properties dialog box. Under region by cells analysis the calculation considers only the region intersecting pings of an interval. This value will also be output for the Layer Heave_min.

This variable is exported only if it is selected on the Export page of the EV File Properties dialog box.
