sentences:  The CCD was a frame transfer device which allowed three gain states (150, 350, and 1000 electrons/bit).Integration times varied from 1–40 ms depending on gain state, solar [[illumination angle]], and filter.The filter center wavelengths (and bandpass widths (FWHM)) were 415 nm (40 nm), 750 nm (10 nm), 900 nm (30 nm), 950 nm (30 nm), 1000 nm (30 nm), and a broad-band filter covering 400–950 nm.
