Check units on all derivatives

[denriquezfirestorm]

It seems the derivative values are all in different units depending on the data value. Worth adding function options like units="deg" to allow the user to specify what units should be used on which derivatives. This was in 1.4.2, not sure if this was changed.

Thanks for the post. This is currently the behavior still.
OptVL outputs alpha and beta in degrees because AVL uses those units for IO. OptVL also uses radians internally.

Would it work for your use case to add this option for Alpha/Beta only? That way at least one could get a consistent set of units.
