     * <p>Noise model coefficients for each CFA mosaic channel.</p>

     * <p>This tag contains two noise model coefficients for each CFA channel

     * corresponding to the sensor amplification (S) and sensor readout

     * noise (O).  These are given as pairs of coefficients for each channel

     * in the same order as channels listed for the CFA layout tag

     * (see {@link CameraCharacteristics#SENSOR_INFO_COLOR_FILTER_ARRANGEMENT android.sensor.info.colorFilterArrangement}).  This is

     * represented as an array of Pair&lt;Double, Double&gt;, where

     * the first member of the Pair at index n is the S coefficient and the

     * second member is the O coefficient for the nth color channel in the CFA.</p>

     * <p>These coefficients are used in a two parameter noise model to describe

     * the amount of noise present in the image for each CFA channel.  The

     * noise model used here is:</p>

     * <p>N(x) = sqrt(Sx + O)</p>

     * <p>Where x represents the recorded signal of a CFA channel normalized to

     * the range [0, 1], and S and O are the noise model coeffiecients for

     * that channel.</p>

     * <p>A more detailed description of the noise model can be found in the

     * Adobe DNG specification for the NoiseProfile tag.</p>

     * <p><b>Optional</b> - This value may be {@code null} on some devices.</p>
