Comment(by hamish):
yeah, looking at the results for day=1 and 30 there's significantly more
light showing on the true-south side of Erebus at that time of year. To
test if that's a counter-intuitive cumulative time-spent effect or not,
next things to try I think are to plot the sun's position through the day,
and try it in another Antarctic stereographic projection that puts grid-
north and true-north in alignment and see if we get the same result.
