I hadn't seen that; shame on me for not doing my due-diligence. However,
their plots look significantly worse than ours do, even if they're
cherry-picking bad pixels. For comparison, here's our 7 worst (most
And here's our sensor-wide average low-end nonlinearity (note that camera
baseline is 100 counts):
I don't have a plot of the least-linear low-end pixels handy.
Thanks again for the help! map_coordinates is a confusing function, but I
have confidence I'll sort it out sooner or later.
