Used hand-held behind a passenger window with exposure times 1/1000s. The camera uses a SONYTM ICX413AQ CCD detector with image format 3040 x 2014 pixels of size: 7.8 microns <P> <B>Heritage</B>: The camera was deployed during the Genesis SRC entry and a similar camera was used for aurora images during the 2002 Leonid MAC mission. <P> <B>Aircraft hardware requirements</B>: None. Hand-held. <P> <B>Instrument validation tests:</B> Used successfully during Genesis SRC entry. <P> <B>Sensitivity</B>: The Genesis SRC entry was detected much above the sensitivity level of the camera in 1/1000s. Gain at ISO 400: 2.57 e-/ADU; RMS noise at ISO 400: 13 e-; Peak dark current at 22oC (typical): 8 ADU/sec/pixel; Offset level (observed electronic bias): 0 ADU (clipped to zero) in Mode 1, 5 ADU in Mode 3. <P> <B>Dynamic range</B>: 12-bit (factor 4095). <P> <B>Frame rate and exposure times</B>: Adjustable exposure time settings, manual and automatic. Rate of capture: about 1 image per second. Best results during Genesis SRC entry for 1/1000s exposure. Time code of the camera's internal clock was calibrated to GPS timing, set by hand to < ÿý0.3s accuracy. <P> <B>Spectral resolution</B> <I>- gives the FWHM of an instrument-broadened unresolved atomic spectral line:</I> <BR>none <P> <B>Relative spectral response</B> - gives the wavelength dependence of the camera + lens.
