The initial default depth is 0.05 MHz. 1 adds one line of output showing the frequency range and the polynomial coefficients calculated at each step. 4 to 9 show the data used at each step, and the calculated polynomial coefficients. LIST negative suppresses most trace output below the first peak. The arrays FV , HT contain the calculated frequencies and real heights.
N gives the number of calculated real-height data points.
This is equal to the sub-peak electron content divided by the peak density. A negative value of SH shows that a model value was used for the scale height, to limit an unreasonable peak extrapolation. All Modes include an estimated start correction, a Chapman-layer peak, and a model valley between layers. The basic parameters which define the type of analysis depend on the parameter MODE , and are obtained from the arrays given below. NT is the number of terms used in the polynomial representation of each real-height segment.
