USER GUIDE
The height to the top of the array and distance from the origin is also shown and can be edited to match the physical deployment
of the system, very useful if for example it wasn't possible to fly the array exactly where you planned, perhaps the points couldn't
be placed as high as you wanted.
The tilt of the entire array is shown and will be automatically generated as part of the optimisation process. It is also possible to
overwrite this if necessary to match the actual tilt of the array, given the resolution of most chain hoists it is frequently difficult
to exactly match a given tilt angle even with front and back motors.
The number of enclosures can also be edited at this stage. Perhaps a cabinet has been damaged in transit and won't physically
attach to the array or perhaps you decide to add MLD cabinets to the bottom of an MLA array you can over-type the number
shown to the maximum number allowed.

Array Diagram

The Array diagram shows a representation of the array and most importantly for flown arrays shows the lower trim point, the
distance from the lowest point on the array to the ground. The diagram will adjust in real time when the optimisation is taking
place and the lower trim will change accordingly. In most instances the lower trim at the start will be lower than when the
optimisation is complete. This is because the array starting point is with an almost straight array with all angles at 0.5⁰, once the
optimisation is complete some of the angles will inevitably be higher thus reducing the overall height of the array and raising the
lower trim height

Optimisation

The Optimisation section is where the optimisation characteristics are defined. The splay coefficients determine the priority
given to either the target response or the leakage. The actual numbers entered are not important, it is the ratio between them
that determine how much priority is given to each coefficient so if you want the Target coefficient to be twice as important as
Leakage you can enter '2' in Target and leave leakage as '1' or you could leave Target as '1' and change Leakage to '0.5' the result
would be exactly the same.
