Changed line 16 from:
TR_OPEN specifies how the initial conditions of the reference trajectory are relative to the final set point targets. An option of 0.0 specifies that the initial conditions for the trajectories should collapse to a single starting value. The near-term trajectory is therefore very prescriptive but then opens up as the trajectory progresses towards steady state targets. An option of 2.0 specifies that the initial opening is twice the separation of [[Main/OptionSphi|SPHI]] and [[Main/Option|SPLO]]. By default, the option of 1.0 is the shape of a tunnel that is of equal width as it progresses towards [[Main/OptionSphi|SPHI]] and [[Main/Option|SPLO]] targets.
