Match Ping Times

This operator selects pings from the first operand in such a way as to match the times of the pings in the second operand. The resulting variable will have one ping for every ping in the second operand. The data for that ping will however come from the ping in the first operand with the nearest ping time. The "allowed slop" is the maximum allowable difference in ping times between the two operands for a successful match. If no successful match is found, then that ping in the second operand does not appear in the resulting echogram.

You enter the processing settings for this operator on the Match ping times page of the Variable Properties dialog box.

Echoview accepts operands of the following data types as input:

Description

Allowed slop

The maximum allowable difference in ping times between the two operands for a successful match. If no successful match is found, then that ping from the second operand does not appear in the resulting echogram.
