The trivial solution involves the adjustment of the assumed rate of horizontal gene transfer to the data (another ad hoc adjustment), but though a very frequent HGT is probable amongst microbes, one must extend it to ...

... by at least 0.6 arc-minutes (0.01.Degrees). This gives an equivalent pixel size of 0.3 arc-minutes. If you take a conservative 120 degrees as your horizontal field of view and 60 degrees in the vertical plane, this translates to ... 576 megapixels of available image data. Curiously - as a counterpoint ...
