Composed with rigorous perfectionism, they are a bit like jazz, allowing a slight aberration in form to revel in its reverberations.
If only a few atypical cells were present, or if cells showed only slight aberrations, smears were categorised as 'uncertain'.
There were also some slight focus aberrations that occurred when shooting quickly but were difficult to reproduce.
There is actually a pretty significant community of people who design these things, making them ever more accurate, adding slight distortion to simulate the glass of the old sets, traveling distortions, tweakable chromatic aberration, all that stuff.
In order to use the triplet type, we relaxed the requirement for chromatic aberration correction and allowed slight focus shifts for different filters.
Each computer-generated hologram (CGH) in the SCGHE is coded with a single particular Zernike aberration mode, and arranged in parallel to one another with a slight separation.
Furthermore, the slight increase in HyPer5 signal did not alter the ratios significantly to impact aberration detection in array CGH experiments.
