Running angle explained

In mathematics, the running angle is the angle of consecutive vectors

(Xt,Yt) with respect to the base line, i.e.\phi(t) = \arctan\left( (\Delta Yt)/(\Delta Xt) \right) .

Usually, it is more informative to compute it using a four-quadrant version of the arctan function in a mathematical software library.
