it's clear that the vfast settings for S2 just aren't
quite right for H1 -- the PSFs are somewhat trefoil
in addition to just being worse -- conundrum is that
this will really drive program overheads if vfast is
needed for each field change

but not a full explanation because the overall seeing
scale is getting monotonically worse with each frame,
which the mirror should not be doing...
