Non-quantized data is 12 bit data are stored as 16 bit values with the upper nibble padded with zeros. The NAVCAM has an on-board quantization process that converts 12 bit data from the CCD into 8 bit data for transmission. This conversion is a square-root style quantization process and there is loss. Consult the calibration documentation to unpack the 8 bit data into its 12 bit approximations.

This value is controlled only by spacecraft commands. When a command is received from the spacecraft to set the bulb_mode value to 0, the shutter is closed.
