PA = conventional mathematical angle - 90 deg, right?

@e-koch, could you quickly sanity check this? It's a definition issue.

e-koch commented 6 years ago

Yes, I think you're right. Then the angle is with respect to the x axis.

You'll need to adjust the angle in as_tophat_kernel too.

That was already done, it just was hidden by the noise of other unmerged junk
