Test 4: Cosmological Density Field. The neutral fraction on a slice through the center of the box at t = 0.05 Myr. Starting from the top left and proceeding clockwise are the results from C²-Ray, FTTE, SPHRAY, CRASH. (* the SPH particles were interpolated onto a 128x128 grid to make this plot and so the axes are measured in grid cells)
