For this part, I would do something like:

nColumns = 256 ; the number of columns in your image
mask = dat ge threshhold
regions = label_region(mask)
for r = 1L, max(regions) do begin
ind = where(regions eq r, count)
center = [mean(ind mod nColumns), mean(ind / nColumns)]
endfor

then continue on with Brian's fitting code.
