Note: When using binning other than 1x1, the pixels are combined inside the
CCD before reading and converting the combined pixel charge to a numeric
value. This results in lower overall noise than reading each pixel separately and
combining them mathematically in your computer. With 2x2 binning for
instance, only one pixel value (representing a square of 4 physical pixels) is fed
through the CCD output amplifier resulting in ¼ the noise compared to reading
each of the 1x1 pixels separately.
