Lag correction

  •    Lag correction is for temporal 'alignment' of different data channels.   You are asked for the number of seconds of lag time (for example, if the response of one channel is delayed relative to some other channel).  The channel is 'left-shifted' (time is advanced) by the chosen amount.  On the right end of the trace, a group of samples equal to the lag interval is set to zero.

    The main goal of lag correction is usually to correctly synchronize two channels.  To determine how much lag time to use, follow these steps:
