Suppose we have a laser emitting a beam in the general direction of a target. Let P be the point nearest to the target, along the beam.
"Range" is a word commonly used for the distance to an object. I need terms to label two orthogonal components of this range from the perspective of the laser: the component along the beam (i.e. from the laser source to P), and the component orthogonal to the beam (i.e. from P to the target). My preferred terms would have been "longeral range" and "lateral range" if only "longeral" existed.
An sample sentence would be (in the voice of the laser) "The longeral range of object X is ten meters." This would mean the range of P (from the laser) is ten meters.
