reassignFreq expression and relation with SMD

Dear all,

I am attempting to simulate a protein(1QSU)
using SMD(steered Molecular Dynamics).
And I would you like to control temperature(300K)
using commands "reassignFreq[Temp]".

I want to know expression of command(reassignFreq[Temp])
used in NAMD.

X-PLOR use expression of velocity assignment.
(m_i/2pi/k_b/T_i)^(3/2)*exp(-3*m_i*delta^2/2/k_b/T_i)
http://www.csb.yale.edu/userguides/datamanip/xplor/xplorman/node208.html#SECTION001112000000000000000

Does NAMD use same expression?
And does reassignFreq parameter affect SMD result?

Please, could you recommend a paper or book related to
command(reassignment parameters).

Thanks and regards,
kang hee.
