  DESCRIPTION = "A JPEG format browse image based on a SHARAD RDR data product.
                 The real and imaginary parts of the signal are used
                 for evaluating the absolute value of the signal
                       sig = sqrt (re^2 + im^2)
                 The sig values is first normalised in the [0-1] range 
                       sig_norm = sig/max(sig)
                 and then the values at 1% (m) and 99% (M) are evaluated.
                 The radargram is saturated at low and high values by using m and M,
                 and the contrast is enhanced with the following algorithm
                       sig_enh = (sig_norm - m) ./ (M - m)
                 Finally, the radargram is shifted to adjust for the RANGE_SHIFT value."
