function dot_props = extract_dot_properties(XYDiameter, dot_index)
% Function to extract dot properties from sizing results
%
% INPUTS:
% XYDiameter: array from sizing results
% dot_index: index of the dot for which the properties are to be extracted
%
% OUTPUTS:
% dot_props: a structure containing the following properties
% X, Y : dot co-ordinates on the image (pix.)
% d_x, d_y: dot diameters along the x and y (pix.)
% I: dot peak intensity (AU)
% R: correlation coefficient - measure of dot tilt
