Comment: update FOV table

...

Typically, SoloHI images will have one of 3 typical FOVs defined below. These are used in the observing programs/modes currently defined but could be changed in-flight if necessary.

e.g. 5º to 25º x 40º (inner) + 25º to 45º x 40º (outer) at perihelion,
each with different cadence. Details in table below.
