Relative density of sources detected over the CFHT/MegaCam field of view. All stars with magnitudes ﹩20\lt g\lt 23﹩ that lie outside the Palomar 5 CMD selection box were used to construct this star-counts “flat.” The tapering of the number of detected stars toward the edges of the instrument is primarily a result of the poorer image quality away from the optical axis of the camera.
