Distribution of the samples of the LGS. Top image: position of each sample of the LGS in the sky for a 40 m telescope with the laser pointing parallel to the pointing of the telescope. Bottom image: relative angular position of each sample with respect to the center of mass of the set of samples. The color of each sample corresponds to its probability density with respect to the most probable sample. A corner from both images was cut to show the inside of the LGS. The shadow on the bottom is there to show how the corner was cut from the LGS to show the inside and also to show the dimensions of the source.
