about half the cells are rampy, the other half are still choice-separated but either flat or both ramping down.
of the rampy ones, about half have spatial structure. and in all but a couple of cases, the targets are all well-placed.
of the non-rampy ones, about half have spatial structure as well. but about half the cells have the targets not well-placed, as well as the stimulus at least nicking a blue-ish region. this seems to be almost all the cells that are down-ramping as well.
so down-ramping = bad target placement + stimulus in blue region
rampy = good target placement + stimulus in red region
