Trying to get a 'zeronoise' image

I have been playing around with the hugin_executor scripting capability
recently added to the default branch of the source repo, and particularly
testing the 'zeronoise' script.
I am having some trouble getting a reasonable result.
I have two input images, 6016x4000. They are not the best test set as they
have been shot handheld.
I pass the test images to align_image_stack, which produces two aligned
images at 6016x4000.
I then run pto_gen to produce a .pto file to pass to hugin_executor. A
look inside this .pto shows the default output is 3000x1500.
I run hugin_executor calling the zeronoise.executor script.
The output produced by the script is 3000x1500, and this image contains a
quite small image in a (lot of) transparent background...not quite what
If I modify the zeronoise.executor script to set nona to save TIFF instead
of TIFF_m and set --save-intermediate-images, I see that the exposure
clipped images are 450x317, which is close to the size of the final
zeronoise output image within the great expanse of transparency, but hard
to be sure as the final output looks to be equirectangular.
I have been running the whole process via this shell script...
# test zeronoise tools in hugin-2015.1.0
# Terry Duell Jul 2015
# test images were shot handheld, so use align_image_stack
align_image_stack -v -a AIS IMGP0223.JPG IMGP0225.JPG
echo " stack aligned"
# generate a .pto file
pto_gen -o zeron.pto AIS*
echo " generated .pto"
# run hugin_executor using zero-noise script
hugin_executor -s -p ZN -u zeronoise.executor zeron.pto
echo "All done!"
Has anyone had any success or otherwise with generating a 'zeronoise'
image using the zeronoise.executor script?
