cpclean does not work with fixed threshold. The threshold is always
mean+n*sigma (in step 1 for each image pair and then in step 2 for the
whole pano). The max-distance factor is the variable n in the given
expression.
Also running autooptimiser in between does not affect the results because
cpclean does its own optimisation for each step before calculating mean and
sigma.

cpclean --help
<snip>
Step 1 optimises all images pairs, calculates for each pair mean
and standard deviation and removes all control points
with error bigger than mean+n*sigma
Step 2 optimises the whole panorama, calculates mean and standard deviation
for all control points and removes all control points with error
bigger than mean+n*sigma

I have extended also the help file for cpclean.
