followup question on error calculation in ABF

Hi all,
I am trying to use formula (22) in JCP 121(7), 2004 to calculate the
error in my ABF data.
 From the simulations, I have the distributions of the instantaneous
force for every bin.
Therefore, I am calculating sigma(F_{e,i}) fitting these distributions
with a Gaussian.

My problem is: I understand the definition of "sampling ratio" (1+2k)
but I don't know how to
calculate it since I don't have the values of the instantaneous force.
I think I'm missing something very simple here ... :o)

Giovanni
