    Please, pay attention to this paper:
    http://sail.msfc.nasa.gov/current_solar_report/CurRpt.pdf

    In particular I am interesting in Table 3.
    I know the percentile of F10.7 and Ap.
    I would understand if it is possible build a curve of probability,
    starting from the previous data.
    I don't think it is possible, therefore I try a different approach to
    evaluate F10.7 and Ap.

    Let's say this paper:
    http://orbitaldebris.jsc.nasa.gov/newsletter/pdfs/ODQNv10i2.pdf
    At pag 4. we can read : "The fitting technique simultaneously
    determines 14 coefficients. These
    include 12 sine/cosine terms plus the average period and a constant
    average flux term".

    Starting from table 3 of the previous paper, how can I determine this
    fitting relation?
    I need a general form at least, so I could find the 14 coefficients by
    a software (e.g. MATLAB statistical toolbox)
    Or also this task is impossible and I should look for a further paper
    that is more precise about this relation?
    However any method to interpolate these data is welcome.
