When MakeProfiles is given a small profile with a strong gradient (such that
all the pixels need monte carlo integration: which has a random element!), in
some cases, it can continue building the profile after the truncation radius!
Here is one example:


$ export GSL_RNG_SEED=1734579442
$ export GSL_RNG_TYPE=ranlxs1
$ echo "1 10.15 10.30 1 0.262 1 -62.41 0.36 27.62 3.67" | astmkprof
--mergedsize=20,20 --zeropoint=25 -o prof.fits --envseed


And image of the output is shown in the next comment.
