As former Zooniverse user you have peeked my interest. Unfortunately I have no numpy experience, so I'm not sure the following might help.
At your 3e and 4e inner loops your using compares like
One could try to limit that to one compare by using pre-ordered-value variables. ie
This part only give a minor (potential trivial) speed gain, its the fact that you can test and preset those high0 & low0 variables before you enter the loop where you do those compares that makes this potential interesting to gain some speed.
With high0 and low0 being something like:
I'm not sure how much speed gain this gives, probably not that significant. But if applied to all jobs than can be lifted from lower to higher loops, it still might add up.
PS: One other thing. You say
See for example 'New Candidates' case 2 in this asteroidzoo result.

if first0<second0<fourth0 or first0>second0>fourth0:.One could try to limit that to one compare by using pre-ordered-value variables. ie
if low0<second0<high0: or of course if high0>second0<low0:.This part only give a minor (potential trivial) speed gain, its the fact that you can test and preset those high0 & low0 variables before you enter the loop where you do those compares that makes this potential interesting to gain some speed.
With high0 and low0 being something like:
low0=min(first0,fourth0) & high0=max(first0,fourth0)I'm not sure how much speed gain this gives, probably not that significant. But if applied to all jobs than can be lifted from lower to higher loops, it still might add up.
