zz	The current zbuffer value at the place of this pixel
dist	Distance of the pixel from the center of the halo squared. Given in pixels
xn	The x coordinate of the pixel relaticve to the center of the halo. given in pixels
yn	The y coordinate of the pixel relaticve to the center of the halo. given in pixels
