    This class is a placeholder for the computed densities and temperatures.

    Densities are provided as an array d such as:

    • d[0] = He number density (1/m³)
    • d[1] = O number density (1/m³)
    • d[2] = N2 number density (1/m³)
    • d[3] = O2 number density (1/m³)
    • d[4] = Ar number density (1/m³)
    • d[5] = total mass density (kg/m³) (*)
    • d[6] = H number density (1/m³)
    • d[7] = N number density (1/m³)
    • d[8] = anomalous oxygen number density (1/m³)
    Total mass density, d[5], is NOT the same for methods gtd7 and gtd7d:
    • For gtd7: d[5] is the sum of the mass densities of the species He, O, N2, O2, Ar, H and N but does NOT include anomalous oxygen.
    • For gtd7d: d[5] is the "effective total mass density for drag" and is the sum of the mass densities of all species in this model, INCLUDING anomalous oxygen.
    O, H, and N are set to zero below 72.5 km.

    Temperatures are provided as an array t such as:

    • t[0] = exospheric temperature (K)
    • t[1] = temperature at altitude (K)

    t[0] is set to global average for altitudes below 120 km.
    The 120 km gradient is left at global average value for altitudes below 72 km.

    Since:
    9.0
