weighting function

Hi R sig geo community!
does the current version of SPGWR use? wij = exp(-(d/h)^2) or wij = 
exp(-0.5*(d/h)^2)as weighting function?
Thanks,
Mike

R 101? To see what the R code does, enter the name of the function at the 
prompt. The default weighting function is gwr.Gauss (see ?gwr), so:

gwr.Gauss

function (dist2, bandwidth)
{
     w <- exp((-0.5) * ((dist2)/(bandwidth^2)))
     w
}

and ?gwr.Gauss says:

dist2: vector of squared distances between observations and fit point

Until 0.5, gwr.gauss was used, as the help page says; the current release 
is 0.6-21.
