<name>Ionogram Scaling: 1D vertical Ne profile calculated as shifted Chebyshev polynomials</name>
<description>
This is a Digisonde-specific computation of the 1D vertical profile of ionospheric electron density given the signal
traces extracted from a vertical-incidence Digisonde ionogram. The technique uses techniques have emerged to accomplish this computation. Most of the approaches use a
iterative fitting algorithm to compare how a profile candidate matches the ionogram by comparing profile-restored and
ionogram-observed traces of the signal reflection. The basic description of profile computation is free from specific detail of the techniques
and details of their capability, but rather states the set of fundamental process capability to report observed properties
of a generic 1D Ne(h) profile.
