% Computes the solar flux prediction based on Julian date.
The outputs of this function may be used by AtmJ70. Stores the data in a
persistent variable. Clear the function to reload.
The database may be updated from a new history file using
LoadSolarFluxHistory.
Has a built-in demo that plots for no outputs.

Form:
jDend = SolarFluxHistorical; % last valid date
d = SolarFluxHistorical( jD )
[aP, f, fHat, fHat400] = SolarFluxHistorical( jD )

Inputs

Outputs
-------
aP (1,1) Geomagnetic index 6.7 hours before the computation
f (3,1) Daily 10.7 cm solar flux (e-22 watts/m^2/cycle/sec)
fHat (3,1) 81-day mean of f (e-22 watts/m^2/cycle/sec)
fHat400 (3,1) fHat 400 days before computation date
- or -
d (.) Data structure for ingestion by AtmJ70. JD form:
.jD (1) Input Julian date
.rECI (3,1) ECI position
.aP (1,1) Geomagnetic index
.f (1,1) Daily 10.7 cm solar flux
.fHat (1,1) 81-day mean of f
.fHat400 (1,1) fHat 400 days before
