foF2 =The
ordinary wave critical frequency of the highest stratification in
the F region
foF1 = The ordinary wave F1 critical frequency
foE = The ordinary wave critical frequency
of the lowest thick layer which causes a discontinuity
fxI = The top frequency of spread F traces
foEs = The highest ordinary wave frequency at
which a mainly continuous Es trace is observed
fmin = The lowest frequency at which echo traces
are observed on the ionogram
MUF(D) = The
standard transmission curve for 3000 km
M(D) = The maximum usable frequency at a defined
distance divided by the critical frequency of that layer
h'F = The
minimum virtual height of the ordinary wave trace taken as a
whole
h'F2 = The minimum virtual height of the
ordinary wave trace for the highest stable stratification in the
F region
h'E = The minimum virtual height of the normal E
layer trace
h'Es = The minimum height of the trace used to
give foEs
hmF2 = peak
height, truncated
hmF1 = peak height
hmE = peak height
yF2 = Parabolic F2 layer semi-thickness
yF1 = Parabolic F1 layer semi-thickness
yE = Parabolic E layer semi-thickness
B0 = Coefficient A0, truncated to integer
km
B1 = IRI Profile Shape parameter
