Polar Transform of Cartesian ( X,Y ) fluorescence data. The polar transformation is a method that converts Cartesian (X,Y) coordinates into their angular (θ) and magnitude (r) components. Each coordinate (X and Y) can be written as the product of its magnitude and angle components, i.e. X= r cos(θ) and Y = r cos(θ). From these expressions, we can solve for and
