From Measure, Value and uvw
A MVuvw is a 3-vector of uvws in a rectangular frame with internal units of m.
It can be constructed with:
MVuvw(Quantity, Quantum<Vector<Double> >)
creates a MVuvw from angle vector, using first two angles, and assuming second as zero if not present. MVuvw(Quantum<Vector<Double> >
creates from angles or uvws, depending on the units in the quantum vector. In the angle case, the data derived can be scaled with the readjust() function. If the unit of the quantum vector is length, uvw is assumed. MVuvw(Vector<Double>
creates from angles (less than or equal to two elements) or x,y,z (3 elements). MVuvw(Vector<Quantity>
creates from length+angles, angles, or x,y,z, depending on units. MVuvw(MVBaseline, MVDirection)
creates a uvw in the specified reference direction (in same reference frame) A void adjust(Double) function normalises the vector to a length of 1; a get() returns as a Double 3-vector the length and angles of the uvw vector; a getAngle() returns a Quantum 2-vector, (uInt) returns the indicated element, and getValue returns the vector.
uvws can be added and subtracted.
The multiplication of two uvws produces the in-product.
