That density is a constant, namely . di normalden(0) .39894228 Whatever mean a normal has just shifts the distribution left or right, so makes no difference to what the peak density is; hence without loss of generality we can focus on mean 0. Whatever SD a normal has, 0/SD is still 0. Correct me if I'm wrong....
