A class holding correlation coefficients for a set of background pixels. CorrelationMatrix is a dataclass that is initialized with a numpy ndarray and provides some convenience methods for accessing the matrix elements. A CorrelationMatrix instance is callable wth two integer values x and y, which returns the <I(m,n) I(m+x, n+y) / sqrt( V(m,n) V(m+x,n+y) )>, where I is the image, V is the variance plane and < > denotes the expectation operator. Parameters ---------- array : `numpy.ndarray` The matrix of correlation coefficients.
