Positions of the six pulsars in the GC M13, marked with red circles with letters. The green crosses are a qLMXB and a cataclysmic variable, which are also labeled in the plot. The center of M13 is shown as a blue cross. The small circle in the middle is the core of M13 and the large circle is the half-light radius of M13. The background is the X-ray image of M13 from the Chandra X-ray Observatory archive (OBsID 5436). The position errors of each source are too small to manifest on the plot. Ordered by descending DM the pulsars are M13E, M13D, M13A, M13F, M13C, and M13B.
