Pike F-1100: frame rate formula dual-tap
All frame rates are valid for AOI top = 0. For AOIs with different positions the
values may differ very slightly (first position after decimal point).
AOI frame rates maxBPP=8192, dual -tap, no sub-sampling
Formula 17: Pike F-1100 : theoretical max. frame rate of CCD (maxBPP=8192, dual -tap, no subsampl.)
