Source X and Y coordinates

The position of a source on the image (XPOS and YPOS) are referred to a coordinate origin in which the pixel at the far-left and bottom of the image has coordinates 1.0, 1.0. The source barycentre coordinates are computed using the first-order moments of the intensity profile.
