Hello, 

I am using YT to cast rays within some galaxies simulated using ENZO. I am using YTray for the purpose. But I am not sure if there is any way to save the array of cell width through which the rays are passing. I know there are some quantities like ('index', 'radius'), ('index', 'spherical_radius'), ('index', 'virial_radius_fraction'). But I am not sure exactly which one of them is the width of the cell. Any help would be appreciated. Thanking you in advance,
