The command Distance_Parallel_To_Path computes the dot product of a vector from the start to point p, with the straight line path defined as the Position at Event1 to position at Event2

In the above figure, the blue line is the parallel distance from the point P. For example:

Distance_Parallel_To_Path

/SIGNAL_TYPES=TARGET

/SIGNAL_NAMES=MID_PSIS

! /SIGNAL_FOLDER=ORIGINAL

/RESULT_NAME=PSIS_DISTANCE

! /RESULT_FOLDER=PROCESSED

/EVENT_NAME_START=START

/EVENT_NAME_STOP=STOP

/NORMALIZE_TO_DISTANCE=FALSE

;

Normalize to distance results in dividing the resulting parallel distance to the distance along the straight path.
