Question

    G.09 - How to quickly evaluate the capabilities of the UNILIB library ?

Answer

    The UNILIB library tool is a collection of FORTRAN modules that usually can only be linked and executed by the use of a FORTRAN main programme (see the examples) or by the use of IDL/PV-WAVE external calls (see the FAQ T.05). In order to allow a quick test or evaluation of the UNILIB library tool, the illustration below includes a query form that controls the computation of the magnetic field intensity and vector, McIlwain's L parameter, the magnetic local time (MLT) and the third adiabatic invariant (Phi). Please note, this computation involves magnetic field line and drift shell tracing that could be time consuming.

Illustration

    The following query activates a FORTRAN programme that makes use of different routines of the UNILIB library(*). The results of the query will be sent by e-mail(**).
    Magnetic field model
    and  
    Planetary magnetic activity index Kp (0 to 9)
    Disturbance storm-time index Dst [2nT] (-600 to 50)
    Solar wind pressure [nP] (0.5 to 10)
    Solar wind density [cm-3] (1 to 100)
    Solar wind velocity [km/s] (100 to 1200)
    Interplanetary magnetic field Y component [nT] (-50 to 50)
    Interplanetary magnetic field Z component [nT] (-50 to 50)
