Jeans mass calculated with different combination of parameters involved has shown interesting variation with remarkable shifting of position of peak value from x = m/T = 0.5 to 5.5. The standard deviation is 2.217. In particular, using the harmonic mean square velocity, shifts the peak Jeans mass to x = m/T ~ 2, which is remarkably less than previously reported value of 4.2. Different scales of neutrino structures including virialized moments have also been compared.
